Select the correct statement for the cell Pt(s)H2g, 1 bar H+aq, 1 MZn2+aq,1 MZnGiven, Zn2+/Zn=-0.76 V
emf of the cell = + 0.76 V
Zn2+aq,1 M+2e-→Zns
hydrogen ion can reduce zinc
All of the above
Ecello=EZn2+/Zn-EH2/2H+o=0.76-0=-0.76 VThus, hydrogen ions can only oxidise zinc and get reduced by them.
