NEETChemistryIonic Equilibrium
Assertion (A) : The aqueous solution of CH ₃ COONa is alkaline in nature. Reason (R) : Acetate ion undergoes anionic hydrolysis The correct answer is
Options
- Aboth (A) and (R) are true and (R) is the correct explanation of (A).
- Bboth (A) and (R) are true but (R) is not the correct explanation of (A).
- C(A) is true but (R) is not true.
- D(A) is not true but (R) is true.
Correct answer
A. both (A) and (R) are true and (R) is the correct explanation of (A).
Step-by-step solution
CH ₃ COONa + H ₂ O CH ₃ COOH + NaOH The above process takes place in following steps CH ₃ COONa in aqueous solution Ionisation CH ₃ COOO ⁻+ Na ⁺ CH ₃ COO ⁻+ H ₂ O CH ₃ COOH + OH ⁻ Acetate ion undergoes anionic hydrolysis and the resulting solution is slightly basic due to excess of OH ⁻ ions. Hence, both (A) and (R) are true and (R) is the correct explanation of (A).
