Normality

Normality

### Formula:

$$N=\frac{\text{Number of Equivalents}}{\text{Volume of Solution in Litres}}$$

### Terminologies:

- N → Normality; concentration expressed as equivalents per litre.

- Equivalents → Reactive amount of solute.

- Volume → Amount of solution present.

### Usage:

- Used in titration and reaction-based calculations.
