a) CuSO4.5H2O is blue in color before heating it.
It turns white in color when it is heated as it loses water molecules attached to it.

CuSO4.5H2O -----> CuSO4 + 5H2O

b) the source of the liquid droplets which are seen on the upper side of test tube is the hydrous CuSO4 crystals. ( these have water molecules attached to them. )
