Q44.Which one of the following when dissolved in water gives coloured solution in nitrogen atmosphere? (1) Cu2 Cl2 (2) ZnCl2 (3) CuCl2 (4) AgCl
What This Question Tests
This question tests the ability to identify transition metal compounds that form colored solutions based on their electronic configuration and stability in aqueous environments under specific conditions (nitrogen atmosphere suggesting exclusion of air/oxygen).
