A blue solution of copper sulphate becomes darker when treated with excess of ammonia. This is because –
ammonia molecules replace water molecules in the solution
ammonia is stronger ligand than water
ammonia forms a stable complex ion [Cu(NH3)4]2+ with Cu2+ ions
All are correct
[Cu(H2O)4]SO4. H2O + 4NH4OH → [Cu(NH3)4]SO4 + 9H2O
