The quantity pH stands for the negative logarithm of the H⁺ ions concentration in a solution. In equation form, pH = - log[H⁺], where [H⁺] is the concentration of hydrogen ion in molarity or moles/liter. Using this definition, the pH of the following substances are:

Oven Cleaner: pH = - log (10⁻¹³ M) = 13

Water: pH = - log (0.0000007 M) = 6.15

Blood: pH = - log (0.00000004 M) = 7.40

Vinegar: pH = - log (0.0063 M) = 2.2

The measure of the pH is important when it comes to reactions because pH is a strong factor. The net charge of a substance is a result of its pH. This charge is the basis of the degree of intermolecular forces like electrostatic attraction due to difference of charges by the substance and its substrate.
