Question From - NCERT Chemistry Class 10 Chapter 03 Question – 022 METALS AND NON-METALS CBSE, RBSE, UP, MP, BIHAR BOARDQUESTION TEXT:-Name two metals which.

When zinc is added to copper sulphate (CuSO4) solution due to more reactivity of zinc, copper is replaced by zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless.

According to the reactivity series, copper is less reactive than zinc. Thus copper cannot displace zinc from its salt solution, but zinc can displace copper from its salt solution. Copper + Zinc sulphate → No reaction Zinc + Copper sulphate → Copper + Zinc sulphate
