Key Equations
Acid Concentration   [H+] = 10-pH
Boyle's Law   P1V1 = P2V2

Charles' Law    V1T2 = V2T1

Ptotal = P1 + P2 + P3 + ...... + Pn

Problems You Should Be Able to Solve
Compare the concentrations of chemicals in a  sample of drinking water with the Maximum Acceptable Concentrations (MACs) to determine if the sample is safe to drink.
Calculate the concentration of a particular ion that is present in a water sample.
Calculate the pH of a solution from a [H+]
Calculate [H+] from a pH
Calculate the concentrations of an acid and a base using titration data.
Calculate the hydrogen ion concentration at each stage of a dilution.
Balance chemical equation to represent the reaction of acids and bases.
Solve problems that involve gases using Boyle's law, Charles' law and Dalton's law of partial pressure.
