1 M NaOH solution was slowly added to 1 L of 210 g impure `H_(2)SO_(4)` solution and the following plot was otained. Calculate the percentage purity of `H_(2)SO_(4)` sample.

Explanation

To calculate the percentage purity of the impure H₂SO₄ solution, we can follow these steps:

### Step 1: Understand the Reaction
When NaOH is added to H₂SO₄, a neutralization reaction occurs:
\[ \text{H}_2\text{SO}_4 + 2 \text{NaOH} \rightarrow \text{Na}_2\text{SO}_4 + 2 \text{H}_2\text{O} \]

From the equation, we see that 1 mole of H₂SO₄ reacts with 2 moles of NaOH.
