What is Acidity?
Acidity generally describes how much acid is present in a solution, such as water. The more acid present in water or the more water behaves as an acid, the more water is considered acidic.
How acidic aqueous (water-based) solutions are measured is by pH. The more acid present in the water, the more acidic the solution, and the lower the pH.
