What are some Properties of Solutions?

What are the way dissolving may be increased

Distinguish between saturated and unsaturated

How do solutes have an effect on the solutions (solvents)

ConcentratedDiluteSaturatedUnsaturated

1. Stir the mixture = dissolves quicker

2. Smaller Particle Size = dissolves quicker [Increases Surface Area]

3. Increase the temperature = dissolves quicker + may dissolve more solute

Types of Solution

• Unsaturated

• Dilute• Can dissolve

more solute• There is not

excess solute at the bottom

• Saturated

• Concentrated• Cant dissolve any

more solute• Excess Solute

sinks to the bottom

If the solution is saturated

• The maximum amount of solute is dissolved in the solution

• No more solute can be dissolved• If you add more solute it will sink to the

bottom

How do solutes have an effect on the solutions (solvents)

Lower Freezing Point Temperature• That’s why we throw salt on ice

Raise Boiling Point Temperature• That’s why we put salt in Boiling Water

Antifreeze in your car• Lowers Freezing Point, Raises Boiling Point
