1.

Solutions are homogeneous mixtures.

2.

A solvent like water can dissolve an unlimited amount of solute.

3.

Temperature increases usually decrease the solubility of a substance in water.

4.

A hydrate is a substance that does not dissolve in water.

5.

There is no such thing as a "supersaturated" solution.

6.

Gases do not dissolve in water or other liquids.

7.

When the pressure of a gas over a liquid is raised, the gas solubility increases

8.

The concentration unit of Molarity is the same as moles solute per liter of solution.

9.

A 2 Molar solution results when 2 moles of solute are dissolved in enough water to make 1 liter of solution.

10.

Miscible materials are substances that are mutually soluble, like H₂O and CH₃CH₂OH.

11.

A unsaturated solution can dissolve more solute.

12.

If 20 mL of water and 20 mL of 3 M NaOH are mixed, the new concentraion is 1.5 M NaOH

13.

Water will dissolve all ionic compounds.

14.

Organic compounds like C₁₂H₂₆ have London forces keeping molecules in the liquid.

15.

Water is a polar molecule and is a good solvent for ionic and polar solutes.

16.

Nonpolar substances do not dissolve well in water.

17.

Gas solubility in water decreases when the temperature goes up.

18.

Adding 9 mL of water to 1 mL of 4.0 Molar HCl will cut the concentration by a factor of ten to 0.40 M HCl.

19.

The concentration of a solution after dilution is always reduced by a factor equal to the initial volume of solution divided by the final volume, V_original/ V_final.

20.

Ionic substances dissolve to form electrically conducting solutions.
