  • $(NH_4)_2SO_4.CuSO_4 . 6H_2O$
  • B
    $(NH4)_2SO_4. FeSO_4. 6H_2O$
  • C
    $(NH_4) _2SO_4 . ZnSO_4. 6H_2O$
  • D
    $(NH_4)_2SO_4. NiSO_4. 6H_2O$

Answer

Correct option: A.
$(NH_4)_2SO_4.CuSO_4 . 6H_2O$
a
Double salts are the molecular compounds that exists only in crystal lattice and lose their identity on dissolution in water.

The double salt $\left( NH _4\right)_2 SO _4 \cdot ZnSO _4 \cdot 6 H _2 O$ does not exist.
