The purpose of the pH determination laboratory experiment is to identify the acidity of the solution. There will be unknown samples of liquid solutions to be given and the pH of which will be measured physically using a litmus paper, quantitatively using a pH meter, and computatively by solving the H+ (hydronium ion) and/or OH- (hydroxide ion) concentrations.

To better assist the experiment, the following are some of the useful equations that can be used in order to determine the pH and the relative concentrations of acidic and/or basic solutions.

pH + pOH = 14


pH   = -log [H+]

pOH = -log [OH-]
