What does pH stand for?
The pH scale is a logarithmic scale that usually runs from 1 to 14. It expresses the acidity or alkalinity of a solution. The scale is based on the negative logarithm of hydrogen ion concentration in a solution. Each pH value below 7 means the solution is acidic, each pH value above 7 means the solution is basic, but pH value about 7 means the solution is neutral.
