Zinc rod is dipped in 0.1 M solution of ZnSO4. The salt is 95℅ dissociated at this dilution at 298K.calculate the electrode Potential given that E¢ ( Zn2+|Zn) = - 0.76 V. |
|
Answer» Answer: The electrode reaction is : Zn2+(AQ)+2e−→Zn(s) According to Nernst EQUATION : E=E∘−0.0591nlog1[Mn+(aq)] E=E∘−0.05912log1[Zn2+] Since 0.1 M ZnSO4 solution is 95% DISSOCIATED, [Zn2+]=0.95×0.1=0.095M. E=−0.76−0.05912log1(0.095) =−0.76+0.02955 LOG 0.095=−0.76−0.02955×1.0223 =−0.76−0.0302=−0.7902V. Explanation: |
