Answer 2

Answer:

The pH scale ranges from 0 to 14. The pH of a solution is a measure of its acidity or alkalinity (base). You have probably used litmus paper, paper that has been treated with a natural water-soluble dye so it can be used as a pH indicator, to test how much acid or base (alkalinity) exists in a solution.
