JEE Main Chemistry question

**Statement 1:** Highly charged cations are expected to form the most strongly acidic hydrated cations. **Statement 2:** The acidity of a hydrated metal ion depends on the strength of the bond between the cation and oxygen.

(A)Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1
(B)Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1Correct
(C)Statement 1 is True, Statement 2 is False
(D)Statement 1 is False, Statement 2 is True

Answer: (B)

Solution

Both statements are factually true on their own: trivalent cations, as a group, are indeed more acidic than divalent cations (monovalent cations have negligible acidic character), and a stronger cation–oxygen bond in a hydrated ion weakens the O–H bond, favouring proton release to a
