Addition of excess aqueous ammonia to a pink coloured aqueous solution of MCl2.6H2O (X) and NH4Cl gives an octahedral complex Y in the presence of air. In aqueous solution, complex Y behaves a 1 : 3 electrolyte. Addition of excess aqueous ammonia to a pink coloured aqueous solution of MCl2.6H2O (X) and NH4Cl gives an [...]
