Acidity and alkalinity are terms used to describe the concentration of hydrogen ion (H+) in a solution. It is measured with the pH scale, a set of values usually given as 1 to 14 where 1 is very acidic, 7 in neutral, and 14 is very alkaline. The numbers are the negative log of the H+ ion's mole concentration.
pH is measured with a pH meter or various indicator solutions which change colour at different pH levels.
