Ø Experiment 1 To measure the pH of different samples in the laboratory. Ø Theory The pH scale is a measure of the hydrogen ion concentration. The pH scale ranges from 0 to 14. pH symbol rooted in the French " p ouvoir h ydrogene " (power of hydrogen).It measures the acidity or basicity of a solution. A pH of 7 means it is a neutral solution. Pure water has a pH of 7. A pH of less than 7 means the solution is acidic. A pH of more than 7 means the solution is basic. The less pH, the more acidic the solution is. The more pH, the more basic the solution is. pH stands for the power of H, or the amount of...
