The number of dissociable protons in "orthophosphoric acid" is
- A 3
- B 4
- C 2
- D 1
Answer & Solution
Correct Answer
(A) 3
Step-by-step Solution
Detailed explanation
Orthophosphoric acid is \(\mathrm{H}_3 \mathrm{PO}_4\), It dissociates as follows : (i) \(\mathrm{H}_3 \mathrm{PO}_4 \rightleftharpoons \mathrm{H}_2 \mathrm{PO}_4^{-}+\mathrm{H}^{+}\) (ii) \(\mathrm{H}_2 \mathrm{PO}_4^{-} \rightleftharpoons \mathrm{HPO}_4^{2-}+\mathrm{H}^{+}\)…
