How do you make an acid or a base neutral?

Answer 1

If it is an acid then add a base until the pH level becomes 7, which is neutral. If it is a base, add acid until the pH is seven.

Answer 2

To make an acid or a base neutral, you can add a substance called a neutralizer. For acids, you can add a base (like sodium hydroxide), and for bases, you can add an acid (like hydrochloric acid). The neutralizer will react with the acid or base to form water and a salt, resulting in a neutral pH.
