The brown coating on iron nail is due to
網頁When an iron nail is dipped into it for 30 minutes, brown copper gets deposited over the iron nail and the solution turns to green due to formation of ferrous sulphate. This change in colour takes place because iron gets oxidised by copper and copper gets reduced by iron. CuSO4 + Fe →FeSO4 + Cu This is a slow reaction. 3
