JEE Main 2024 — 27 January, Shift 1 — Question 68
Given below are two statements, one is labelled as Assertion (A) and the other is labelled as Reason (R).
Statement (I) : Aqueous solution of ammonium carbonate is basic.
Statement (II) : Acidic/basic nature of salt solution of a salt of weak acid and weak base depends on and value of acid and the base forming it.
In the light of the above statements, choose the most appropriate answer from the options given below :
- Option A:Correct
Both statement I and statement Il are correct.
- Option B:
Statement I is correct and statement Il is incorrect.
- Option C:
Statement I is incorrect and statement Il is correct.
- Option D:
Both statements 1 and statements ll are incorrect.
Answer: A
Step-by-step solution
Statement (I) is correct: Ammonium carbonate is a salt of a weak acid and a weak base . For such salts, the nature of the aqueous solution depends on the relative values of and . Since, , the aqueous solution is basic.
Statement (II) is correct: For salts formed from a weak acid and a weak base, the acidic or basic nature of the solution depends on the values of and of the acid and base forming the salt.
Thus, both Statement I and Statement II are correct Option A.
