Solution

The correct option is A $C u_{2} [F e (C N)_{6}]$
The reaction can be given as: $2 C u S O_{4} + K_{4} [F e (C N)_{6}] \to C u_{2} F e (C N)_{6} + 2 K_{2} S O_{4}$ .
The product formed $C u_{2} [F e (C N)_{6}]$ is called cupric ferrocyanide. The product obtained is reddish brown precipitate and this reaction is used as a test for $C u^{+ 2}$ .

2CuSO4+K4[Fe(CN)6]⟶A+2K2SO4.A is

The correct option is A Cu2[Fe(CN)6]The reaction can be given as: 2CuSO4+K4[Fe(CN)6]→Cu2Fe(CN)6+2K2SO4. The product formed Cu2[Fe(CN)6] is called cupric ferrocyanide. The product obtained is reddish brown precipitate and this reaction is used as a test for Cu+2.
