Dilution Adding water to a solution in order to decrease the concentration
Dilution equation M1V1=M2V2
When number of moles is divided by volume (in liters), you get _____ molarity
When molarity is multiplied by volume (in liters), you get ______ number of moles
Triation The process of slowly reacting a base of unknown concentration with an acid of known concentration (or vice versa) until just enough acid had been added to react will all of the base. This process determines the concentration of the unknown base (or acid)
