For a gas, solubility will increase if _____ increases.

• Pressure
• Temperature
• Aggitation

Calculate the concentration of 25.0 grams of KBr dissolved in 0.750 L (hint: convert grams to moles)

• 0.280 mol/L

• 0.210 mol/L

• 33.3 mol/L

Define the term insoluble.

• Can dissolve in water.

• Cannot dissolve in water.

• Partially dissolves in water.

How does a solution become supersaturated?

• dissolve lots of solute in it.
• dissolve a little solute in it. 
• dissolve more solute than you should be able to. 
• dissolve a solvent in it.
