What is the pH scale?

Back

A scale that measures how acidic or basic a solution is, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What is a neutral solution?

Back

A solution with a pH of 7, indicating it is neither acidic nor basic.

Front

What happens to the pH of a solution when an acid is added?

Back

The pH decreases, making the solution more acidic.
