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)

Concentraded Dilute Saturated Unsaturated

1.Stir the mixture – dissolves quicker 2.Increase the temperature – dissolves quicker + may dissolve more solute 3.Smaller Particle Size of Solute – dissolves quicker

100 ml water 1 g of CuSO ml water 5 g of CuSO ml water 10 g of CuSO 4

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 HOWEVER, if you raise the temperature, more solute will probably dissolve – that’s called a SUPERSATURATED SOLUTION

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 Boling Point
