How to Calculate pH
In everyday life, pH is a scale generally used to describe the neutrality, or lack of neutrality, in a household item. In science, pH is a measure of ions within a solution. If you’re taking a science or chemistry class, you may need to know how to calculate pH based off concentration instead. Calculate pH by using the pH equation: pH = -log10[H3O].

How to Know if a Liquid Is a Base or an Acid
It is often important to know if you are handling an acid or a base. Acids and bases have different observable properties and act differently when mixed with other substances. The pH scale measures the strength of acids (pH<7.0) and bases (pH>7.0). Measuring pH can also be used as a way to identify acids and bases. If you are unsure of the acidity or basicity of a substance,
