The true statement for the acids of phosphorus, H ₃ PO ₂, H ₃ PO ₃ and H ₃ PO ₄ is

Step-by-step solution

H ₃ PO ₂, H ₃ PO ₃ and H ₃ PO ₄ contain one, two and three ionisable hydrogen atoms respectively. aligned & H ₃ PO ₂ H ⁺+ H ₂ PO ₂⁻ & H ₃ PO ₃ H ⁺+ H ₂ PO ₃ ⁻ 2 H ⁺+ HPO ₃ ²⁻ & H ₃ PO ₄ H ⁺+ H ₂ PO ₄⁻ 2 H ⁺+ HPO ₄ ²⁻ & 3 H ⁺+ PO ₄ ³⁻ aligned But there is very little difference in acidity. As s p^3 hybridised, therefore all are tetrahedral.
