Chemistry

Normality

Calculate normality of a solution.

Normality = Number of gram equivalents / Volume of solution in litres

Formula Explanation

Normality is number of equivalents per litre of solution.

Variables Explained

Gram equivalent = molar mass / n-factor.

Solved Example

0.5 equivalents in 2 L solution. Normality?
0.5 / 2 = 0.25 N.

Exam Tip

For acids, n-factor is number of H⁺ ions.
