Review 2: Molarity and Solubility Curve

Calculate the molarity of the following solution:  1.0 mole of KCl in 750.0 mL of solution.

• 0.750 M
• 99 M
• 1.3 M
• 2.0 M

The ___ is the thing being dissolved

• solute
• solvent

What is the formula for molarity?

• moles/grams
• moles/kilograms
• moles/milliliters
• moles/liters

What is a solvent?

• The substance that does the dissolving in a solution.

• The substance that is being dissolved in a solution.

• The mixing of different substances.

• The process in which neutral molecules lose or gain electrons.

You are given a small beaker of solution at room temp. You add a bit of solute to the solution and it dissolves. The solution was:

• saturated

• unsaturated

• concentrated

• warm

When a solution is saturated:

• No additional material will dissolve in it
• You need to stir it more 
• Two materials have combined to create a clear liquid
• Crystals form 

What are 3 methods to increase the rate of dissolution/dissolving?

• Particle Size

• Temperature

• Evaporation

• Agitation (stirring)

• Arugula

When a solution is saturated:

• No additional material will dissolve in it
• You need to stir it more 
• Two materials have combined to create a clear liquid
• Crystals form
