    pH is a measure of how acidic or basic a chemical is when it's in aqueous (water) solution.A neutral pH value (neither an acid nor a base) is 7. Substances with a pH greater than 7 up to 14 are considered bases. Chemicals with a pH lower than 7 down to 0 are considered acids.The closer the pH is to 0 or 14, the greater its acidity or basicity, respectively.
