Statement 1: On cooling in ice, the blue solution of [Cu(H2O)4]2+ in concentrated HCl turns more yellow-green according to [Cu(H2O)4]2+(aq) + 4Cl-(aq) ⇌ [CuCl4]2-(aq) + 4H2O(l).
Statement 2: The forward reaction is endothermic.
Options:
Answer:
D
Solution:
The forward reaction gives yellow-green [CuCl4]2- and is endothermic, so Statement 2 is correct Cooling favours the exothermic backward direction
This forms more blue [Cu(H2O)4]2+, so the solution turns bluer, not more yellow-green, and Statement 1 is incorrect
Statement 1 is incorrect and Statement 2 is correct, option (d).
