CuSO 4+4 NH 3 arrow[ Cu ( NH 3)4] SO 4 Blue complex due to [ Cu ( NH 3)4]2+

Q. The deep blue colour produced on adding excess of ammonia to copper sulphate is due to presence of

$C u^{2 +}$

$[C u (N H_{3})_{4}]^{2 +}$

$[C u (N H_{3})_{6}]^{2 +}$

$[C u (N H_{3})_{2}]^{2 +}$

$C u S O_{4} + 4 N H_{3} \to [C u (N H_{3})_{4}] S O_{4}$
Blue complex due to $[C u (N H_{3})_{4}]^{2 +}$
