What is the normality of 0.3 M `H_(3)PO_(4)` solution ?

Explanation

To find the normality of a 0.3 M solution of phosphoric acid (H₃PO₄), we can follow these steps:

### Step 1: Understand the concept of Normality
Normality (N) is a measure of concentration equivalent to molarity multiplied by the number of equivalents of the solute. For acids, the number of equivalents is determined by the number of protons (H⁺ ions) that can be donated by the acid.

### Step 2: Determine the basicity of H₃PO₄
Phosphoric acid (H₃PO₄) can donate three protons (H⁺ ions) when it dissociates. Therefore, its basicity is 3.
