Question

Which colour is noticed when copper ia reactef with ferrous sulphate?

Answer 1

No colour change can be noticed as iron is more reactive than copper. So displacement reaction is not possible. Formation of Copper Sulphate is thus not possible, which doesn't allow color change to take place.

Answer 2

The reaction between copper and ferrous sulphate does not occur since copper is unable to displace iron from its solution. Iron is highly reactive than copper and therefore we expect the solution to retain its color.

However, the colour of the copper sulphate solution (CuSO₄) will change from blue to light green.
