Question

You take an aqueous solution of CuSO4 in a test tube. Now dip a clean iron nail in CuSO4 solution observe the test tube after 20min? Mention the change in the nail? write the balance chemical equation for the reaction? ​

Answer 1

in this reaction the iron nail turns into brown colour(as iron displaces copper from copper sulphate)

CuSO⁴ + Fe –––> FeSO⁴ + Cu

Answer 2

Answer:

1)the iron nail will become brownish in colour

2) Fe + CUSO4 ------> FESO4 + CU

is the equation for the given reaction
