What is an acid?

Back

An acid is a substance that has a pH less than 7 and can donate protons (H+) in a solution.

Front

What is a base?

Back

A base is a substance that has a pH greater than 7 and can accept protons (H+) in a solution.

Front

What is the pH level of a neutral solution?

Back

The pH level of a neutral solution is 7.

Front

What happens to pH as acidity increases?

Back

As acidity increases, the pH value decreases.

Front

What happens to pH as basicity increases?

Back

As basicity increases, the pH value increases.

Front

What is the pH level of strong acids?

Back

Strong acids typically have a pH level between 0 and 3.

Front

What is the pH level of strong bases?

Back

Strong bases typically have a pH level between 11 and 14.
