WebbWhat is pH? pH is a measure of the acidity and alkalinity properties of an aqueous solution, which are determined by the concentration of hydrogen ions (H +) in the solution. Water has the molecular formula of H 2 O and almost always exists in the stable molecular state of H 2 O. However, a small proportion also exists in the form of ions known ... WebbA pH scale is a tool for measuring acids and bases. The scale ranges from 0-14. Litmus paper is an indicator used to tell if a substance is an acid or a base. The colour of the paper matches up with the numbers on the pH scale to indicate what kind of substance is being tested. For example, Vinegar is an acid and measures 2.4 on the pH scale.
