Given below are two statements : 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 K_a and K_b of acid and the base forming it. In the light of the above statements, choose the most appropriate answer from the options given below : (1) Both statement-I and Statement-II are correct (2) Both statement-I and Statement-II are incorrect (3) Statement-I is correct but Statement-II is incorrect (4) Statement-I is incorrect but Statement-II is correct
- (1) Both statement-I and Statement-II are correct
- (2) Both statement-I and Statement-II are incorrect
- (3) Statement-I is correct but Statement-II is incorrect
- (4) Statement-I is incorrect but Statement-II is correct
Correct answer: (1) Both statement-I and Statement-II are correct
Solution
Ammonium carbonate in solution dissociates to produce ammonium ions, which can accept protons, making the solution basic. Additionally, the nature of a salt solution formed from a weak acid and weak base is indeed determined by the dissociation constants (K_a and K_b) of the respective acid and base, confirming both statements are correct.
