To determine how many moles of NaOH are required to neutralize 1 mole of H₃PO₃ (phosphorous acid), we need to analyze the acidic nature of H₃PO₃ and how it reacts with NaOH. ### Step-by-Step Solution: 1. **Identify the Acidic Protons in H₃PO₃:** H₃PO₃ has three hydrogen atoms, but not all of them are acidic. The structure of H₃PO₃ shows that it has two acidic protons (the ones attached to the oxygen atoms). Therefore, H₃PO₃ can donate two protons (H⁺ ions) in a reaction. 2. **Write the Neutralization Reaction:** ...
