What is a base?

Back

A base is a substance that accepts protons (H+) or donates hydroxide ions (OH-) in a solution and has a pH greater than 7. Examples include baking soda and dishwashing detergent.

What does pH measure?

Back

pH measures the acidity or basicity of a solution on a scale from 0 to 14, where 7 is neutral, below 7 is acidic, and above 7 is basic.
