What are the way dissolving may be increased
Distinguish between saturated and unsaturated
How do solutes have an effect on the solutions (solvents)
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
