(b) What will be the colour change?
(C) Give reason for the change in colour observed.
(d) Write the chemical equation for the reaction.​

Answer 1

Explanation:

c.) Because Displacement Reaction takes place

d.) Fe + CuSO4 = FeSO4 + Cu

Answer 2

Answer:

he will find that the colour of the solution will became light green .

the colour will change because fe will displace cu from the CUSO4 solution.

Fe + CUSO4

FeSo4 +cu

a layer of copper will form on the iron nail.
