How to Measure the pH of Water
Testing the pH of water tells you how acidic or basic the water is at the moment of testing. Pure, unpolluted water normally has a pH level of 7, which is neutral (neither acidic nor basic). The pH level of water can provide information on potential contamination and can be an important precaution for protecting the health of people, animals, and vegetation.

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,
