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_("CELL")^(@)=E_("OX")^(@)+E_("red")^(@)=0.44V+0.34V=0.78V` These `+veE_("cell")^(@)` values shows that iorn 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. |
