Outcomes

Remember the products of common

reactions:

Acid + metal

Acid + metal hydroxide

Write balanced ionic equations for the

reactions above

Common reactions

In this four week course we will look at

reactions for:

Ionic compounds dissociating when in water

Ionic compounds precipitating when mixed

Acid + metals

Acid + metal hydroxides

Acids and Bases

Name and formula of common acids:

CH3COOH – Ethanoic acid

H3PO4 – Phosphoric acid

H2SO4 – Sulfuric acid

HNO3 – Nitric acid

H2CO3 – Carbonic acid

HCl – Hydrochloric acid

found on page 35

Bases are those compounds with

hydroxide in them.

Ie: Metal hydroxides

Acids and Bases

Acid and Metal

Reaction of an acid and metal produces

hydrogen gas and a salt

The hydrogen gas is made up of the

hydrogen ions ( ) from the acid.

The salt is made up of the metal ion

(positive) and the negative ion of the

acid

Acid and Metal

The general reaction is:

Acid + metal salt + hydrogen gas

Acid and Metal Hydroxide

(base) Reaction of an acid and metal hydroxide

produces water and a salt

The water is made up of the hydrogen ions

( ) from the acid and hydroxide ( )

ions from the base

The salt is made up of the metal ion

(positive) and the negative ion of the

acid

Acid and Metal Hydroxide

The general reaction is:

Acid + metal hydroxide salt + water
