NEET Chemistry Chemical Equilibrium Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) K_a | (i) Strength of NH3 as a base |
| (b) K_b | (ii) Strength of NH4+ as an acid |
| (c) K_w | (iii) Ion product of water |
| (d) K_a × K_b | (iv) Relationship of conjugate pairs |
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
K_a represents the strength of NH4+ as an acid, K_b represents the strength of NH3 as a base, K_w is the ion product of water, and K_a × K_b shows the relationship of conjugate pairs in equilibrium. This is illustrated in the NCERT context.
