C. A pungent Smelling gas get a liberateel.
(d) asmall bubbles of H2 gas appear on the surface,​

Answer 1

Some of the crystals of anhydrous copper sulfate are dissolved in water the resultant colour of the solution is blue or some times sky blue. The solution turns acidic.

Answer 2

Answer:

on adding zinc to CuSO4 solution, zinc displaces copper from copper sulphate & forms zinc sulphate solution because zinc is more reactive metal which displaces less reactive metal from its solution.

This is indicated by a colour change from blue to colourless. 

CuSO4 solution has a blue colour while ZnSO4 solution is colourless.

Zn+CuSO4→ZnSO4+Cu

Option C is correct.
