What are the uses of sulphuric acid in daily life?There are many uses for the acid including the manufacture of fertilisers, rubber, other acids, detergents, dyes, some medicines and in oil refining. Because it is so widely used in industry, exposure may occur in many work places. Burning fossil fuels also releases sulphur dioxide which can react with water in the air to form sulphuric acid. Sulphuric acid is also used to harvest potatoes; the acid damages the leaves killing the plant and making it easier to lift the potatoes from the ground.

At home the main sources of sulphuric acid are lead-acid car batteries and some solutions forunblocking drains. Sulphuric acid is not persistent in the environment, being quickly neutralised.

Acid rains

Coal-burning power plants are a significant source of Sulphur dioxide (SO2) and nitrogen oxides (NOx), which are

major players in acid rain and ground level ozone (smog). Nitrogen oxides are also greenhouse gasses that react

with organic compounds to form smog, which damages plant life, making it vulnerable to disease and extreme

weather. It can  also impair human health by causing increased risk of asthma, lung damage and premature

death.

Emissions of sulfur dioxide and nitrogen oxides react with water vapor in the atmosphere to create sulfuric and nitric

acids.

Acid rain occurs when SO2 and NOX interact with water, oxygen, and other chemicals in the air to form sulphuric

acid and nitric acid. This toxin can fall from the sky in rain over a widespread area, killing fish and plants. Forests

are also impacted via direct damage to foliage and where forest soils have been stripped of nutrients by acid rain.

The shocking impacts of acid rain on forests around the world have led to progress, in curbing toxic rain in the US

and Europe for example, but it is estimated that acid rain still falls on 30 percent of the land in China, and on

hundreds of its cities.

The fact remains that coal is still by far the single biggest source of sulphur emissions caused by power

generation. In 2004, 95 percent of the 10.3 million tons of SO2, and 90 percent of the 3.9 million tons of NOx,

released into the atmosphere by US power plants came from ones fuelled by coal

Fertilizer & Agriculture 

Agricultural industries are the major users of ammonia, representing nearly 80% of all ammonia produced in the United States.Ammonia is most commonly used as a fertilizer and applied directly to the soil from tanks containing the liquefied gas.Ammonia is a very valuable source of nitrogen that is essential for plant growth.Ammonia is used in the production of liquid fertilizer solutions that consist of ammonia, ammonium nitrate, urea and aqua ammonia.The fertilizer industry also uses ammonia to produce ammonium and nitrate salts.Ammonia and urea are used as a source of protein in livestock feeds for animals such as cattle, sheep and goats.Ammonia is used as a pre-harvest cotton defoliant, an anti-fungal agent on certain fruits and a preservative for the storage of high-moisture corn. 

Ammonia is a colorless gas, and actually has to be dissolved in water before we can use it for these household applications. NEVER use ammonia with bleach or any other product containing chlorine! The fumes are HIGHLY toxic! Work in a well ventilated space and avoid breathing ammonia vapors. Wear rubber gloves and avoid skin contact. Store out of the reach of children.

Remove paint from clothes by saturating the items several times with half ammonia,

half turpentine solution, and then tossing them in the wash.

Use as plant food. Ammonia can be used on alkaline-loving flowering plants and

vegetables like clematis, lilak, hydrangea and cucumbers. Occasionally treat your

plants with a shower of 1/4 cup ammonia mixed with 1 gallon of water.

Stop mosquito bites from itching. If you have not yet scratched the bite open,

put one drop of ammonia directly on the bite.Clean crystal. Bring back the sparkle by mixing a few drops of ammonia in 2 cups water and wiping with a cloth. Rinse in clear water and dry with a different soft cloth.

Nitrogen fertilizer component

1 Ammonia is one nitrogen fertilizer component that can be

synthesized from in-expensive raw materials. Since nitrogen makes

up a significant portion of the earth's atmosphere, a process was

developed to produce ammonia from air. In this process,

natural gas and steam are pumped into a large vessel. Next, air is

pumped into the system, and oxygen is removed by the burning of

natural gas and steam. This leaves primarily nitrogen, hydrogen,

and carbon dioxide. The carbon dioxide is removed and ammonia is

produced by introducing an electric current into the system.

Catalysts such as magnetite (Fe 3 O 4 ) have been used to improve

the speed and efficiency of ammonia synthesis. Any impurities are

removed from the ammonia, and it is stored in tanks until it is

further processed.

2 While ammonia itself is sometimes used as a fertilizer, it is often

converted to other substances for ease of handling. Nitric acid is

produced by first mixing ammonia and air in a tank. In the presence

of a catalyst, a reaction occurs which converts the ammonia to

nitric oxide. The nitric oxide is further reacted in the presence of

water to produce nitric acid.

3 Nitric acid and ammonia are used to make ammonium nitrate.

This material is a good fertilizer component because it has a high

concentration of nitrogen. The two materials are mixed together in

a tank and a neutralization reaction occurs, producing ammonium

nitrate. This material can then be stored until it is ready to be

granulated and blended with the other fertilizer components.

Nitrogen fertilisers

Making nitrogen fertilisers involves producing ammonia, which is then reacted

with oxygen to produce nitric acid. Nitric acid is used to acidify phosphate rock to

produce nitrogen fertilisers. The flow diagram below illustrates the processes that are

involved. Each of these steps will be examined in more detail.

Figure 1: Flow diagram showing steps in the production of nitrogen fertilisers

1. The Haber Process

The Haber process involves the reaction of nitrogen and hydrogen to produce

ammonia. Nitrogen is produced through the fractional distillation of air. Fractional

distillation is the separation of a mixture (remember that air is a mixture of different

gases) into its component parts through various methods. Hydrogen can be

produced through steam reforming. In this process, a hydrocarbon such as

methane reacts with water to form carbon monoxide and hydrogen according to the

following equation:

CH4+H2O→CO+3H2

Nitrogen and hydrogen are then used in the Haber process. The equation for the

Haber process is:

N2(g)+3H2(g)→2NH3(g)(The reaction takes place in the presence of an iron (Fe) catalyst under conditions

of 200 atmospheres (atm) and 450–500 ℃)

Interesting Fact:The Haber process developed in the early 20th century, before the start of World

War 1. Before this, other sources of nitrogen for fertilisers had included saltpeter

(NaNO3) from Chile and guano. Guano is the droppings of seabirds, bats and

seals. By the 20th century, a number of methods had been developed to 'fix'

atmospheric nitrogen. One of these was the Haber process, and it advanced

through the work of two German men, Fritz Haber and Karl Bosch. They worked out

what the best conditions were in order to get a high yield of ammonia, and found

these to be high temperature and high pressure. During World War 1, the ammonia

that was produced through the Haber process was used to make explosives.

2. The Ostwald Process

The Ostwald process is used to produce nitric acid from ammonia. Nitric acid can

then be used in reactions that produce fertilisers. Ammonia is converted to nitric acid

in two stages. First, it is oxidised by heating with oxygen in the presence of a

platinum catalyst to form nitric oxide and water. This step is strongly exothermic,

making it a useful heat source.

4NH3(g)+5O2(g)→4NO(g)+6H2O(g)

Stage two, which combines two reaction steps, is carried out in the presence of

water. Initially nitric oxide is oxidised again to yield nitrogen dioxide:

2NO(g)+O2(g)→2NO2(g)This gas is then absorbed by the water to produce nitric acid. Nitric oxide is also a

product of this reaction. The nitric oxide (NO) is recycled, and the acid is

concentrated to the required strength.

3NO2(g)+H2O(l)→2HNO3(aq)+NO(g)3. The Nitrophosphate Process

The nitrophosphate process involves acidifying phosphate rock with nitric acid to

produce a mixture of phosphoric acid and calcium nitrate:

Ca3(PO4)2+6HNO3+12H2O→2H3PO4+3Ca(NO3)2+12H2O

When calcium nitrate and phosphoric acid react with ammonia, a compound fertiliser

is produced.

Ca(NO3)2+4H3PO4+8NH3→CaHPO4+2NH4NO3+8(NH4)2HPO4

If potassium chloride or potassium sulphate is added, the result will

be NPK fertiliser.

4. Other nitrogen fertilisers

Urea ((NH3)2CO) is a nitrogen-containing chemical product which is

produced on a large scale worldwide. Urea has the highest nitrogen content of

all solid nitrogeneous fertilisers in common use (46,4%) and is produced by

reacting ammonia with carbon dioxide.

Two reactions are involved in producing urea:

1. 2NH3+CO2→H2N−COONH4

2. H2N−COONH4→(NH2)2CO+H2O

Other common fertilisers are ammonium nitrate and ammonium sulphate.

Ammonium nitrate is formed by reacting ammonia with nitric acid.

NH3+HNO3→NH4NO3

Ammonium sulphate is formed by reacting ammonia with sulphuric acid.

2NH3+H2SO4→(NH4)2SO4

Advantage of alloy

Less Weight One of the main benefits of alloy wheels is the fact that they are generally--

but not always--lighter than something like a steel rim. Alloys reduce the unsprung weight of a car's suspension, which is the amount of weight carried by just the suspension. Fitting lighter alloy wheels to a car pays off with an improvement in steering response and agility, particularly during aggressive driving.

More Strength Because of their aluminum construction, alloy wheels are also very strong

and much more resistant to bending than wheels made of other materials such as steel. Alloy wheels dissipate heat better, which minimizes cracking to the metal. This superior heat dissipation can even promote better braking, since heat around the brakes in minimized. Another aspect that contributes to brake cooling is the open construction of many alloys, where air around the spokes lets more air cool the brakes.

Large Selection Because of their tremendous popularity, there is an extremely large selection

of alloy wheels to choose from. It should be kept in mind though that some cars have unusual bolt patterns and therefore have a limited number of alloy wheels that will fit. But for cars with a common bolt pattern like a VW or Honda there are many choices, from as small as a 13-inch wheel to something as large as an 18-inch or even larger.

Better Appearance Aluminum alloys are better looking than standard steel wheels. They come in

a wide variety of finishes, including polished, chromed and painted. You can also order custom alloy wheels from some companies with the finish that you want.

Improve Car's Value Installing a set of alloy wheels will usually improve the value of your vehicle,

or at least its desirability, making it potentially easier to sell. Because alloys have multiple benefits, from increases performance to better looks, they are generally considered a plus when fitted to a car.
