How many moles of NaOH is required to neutralize 1 mole of `H_(3)PO_(3)`

Explanation

To determine how many moles of NaOH are required to neutralize 1 mole of \( H_3PO_3 \) (phosphorous acid), we need to analyze the acidic protons in the molecule and the neutralization reaction.

### Step-by-Step Solution:

1. **Identify the Structure of \( H_3PO_3 \)**:
- The structure of phosphorous acid \( H_3PO_3 \) can be represented as follows:
\[
\text{P} = \text{O} \quad \text{(double bond)}
