The pH scale is a valuable tool for measuring the acidity or alkalinity of substances, with values below 7 indicating acidity, values above 7 indicating alkalinity, and 7 representing neutrality.

On the pH scale, bases range from 7.1 to 14, with higher scores meaning stronger bases. Common bases include seawater (pH 8), baking soda (pH 9.5), all the way to liquid drain cleaner (pH 14). Just as ...
