The EMF of the cell M|Mn+(0.02 M)||H+(1 M)|H2(g)(1 atm),Pt at 25 oC is – InterviewSolution

1.	The EMF of the cell M\|Mn+(0.02 M)\|\|H+(1 M)\|H2(g)(1 atm),Pt at 25 oC is 0.81 V. The valency of the metal if the standard oxidation potential of the metal is 0.76 V?(log0.02=−1.7)
Answer» The EMF of the cell $M \| M^{n +} (0.02 M) \| \| H^{+} (1 M) \| H_{2} (g) (1 a t m), P t$ at $25^{o} C$ is $0.81 V$ . The valency of the metal if the standard oxidation potential of the metal is $0.76 V$ ? ( $log 0.02 = - 1.7$ )
