pH

pH

The pH test measures the acidity or alkalinity of a solution. The pH is measured on a scale of 0 to 14. Solutions with a pH less than 7 are considered acidic, while those with a pH greater than 7 are considered basic (alkaline). A pH of 7 is considered neutral. This test can be used to determine quality control or shelf life stability studies.
