Is it possible to store copper sulphate in an iron vessel for a long time? Given : E_(Cu^(2+)|Cu)^(@)=0.34V " and " E_(Fe^(2+)|Fe)=-0.44V |

Answer» Solution :`(E_("ox")^(@))_(Fe|Fe^(2+))=-0.44V " and " (E_("red")^(@))_(Cu^(2+)|Cu)=0.34V` These +ve emf values SHOWS that iron will OXIDISE and COPPER will get reduced i.e., the vessel will dissolve. HENCE it is not possible to store copper SULPHATE in an iron vessel. |
