`{:(2NaOH+H_(2)SO_(4)rarrNa_(2)SO_(4)+2H_(2)O),("Base Acid"):}`

Explanation

To find the valency factor of sodium hydroxide (NaOH) in the reaction with sulfuric acid (H₂SO₄), we can follow these steps:

### Step 1: Write the balanced chemical equation
The balanced chemical equation for the reaction between sodium hydroxide and sulfuric acid is:
\[ 2 \text{NaOH} + \text{H}_2\text{SO}_4 \rightarrow \text{Na}_2\text{SO}_4 + 2 \text{H}_2\text{O} \]

### Step 2: Identify the components
In this reaction:
