pH Scale

The pH scale is a numerical scale used to specify the acidity or basicity of an aqueous solution, ranging from 0 to 14.

A pH level of 7 indicates a neutral solution.

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

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

Lemon juice typically has a pH level around 2, making it acidic.

Bleach has a pH level of around 13, indicating it is a strong base.

Acids typically taste sour.

Bases typically taste bitter.

The pH level of pure water is 7, which is neutral.

When an acid is added to water, the pH decreases, making the solution more acidic.
