Question

answer the following questions why do the colour and solution of copper sulphate change when we take a solution of copper sulphate in a beaker and put an iron nail in it​

Answer 1

Explanation:

Chemical reaction of iron nail with copper sulphate solution in water. Iron displaces copper ions from an aqueous solution of copper sulphate. It is a single displacement reaction of one metal by another metal. Thus iron is more reactive than copper.

Answer 2

ANSWER

Fe(s)+CCuSO ⟶Cu(s)+FeSO4

When an iron nail is dipped in copper sulphate solution, a brown coating of copper is formed on the surface of iron and the colour of copper sulphate solution changes from blue to light green. This reaction shows that iron is more reactive than copper as it displaces copper from its solution and iron passes into solution as Fe^2+ ions and ferrous sulphate solution is formed.
