Basicity of `H_3PO_2, H_3PO_3 and H_3PO_4` is not the same. Explain

Text Solution

AI Generated Solution

To explain why the basicity of H₃PO₂, H₃PO₃, and H₃PO₄ is not the same, we need to analyze the structure and the number of replaceable hydrogen atoms in each of these oxoacids of phosphorus. ### Step-by-Step Solution: 1. **Understanding the Compounds**: - H₃PO₂ (Phosphorous acid) - H₃PO₃ (Phosphoric acid) - H₃PO₄ (Phosphoric acid) ...
