In some applications nickel-cadmium batteries have been replaced by nickel-zinc batteries. the overall cell reaction for this relatively new battery is: 2h2o(l)+2nio(oh)(s)+zn(s)→2ni(oh)2( s)+zn(oh)2(s)standard reduction potentials in water at 25 ∘ce∘red(v) reduction half-reaction-0.28 ni2+(aq)+2e−→ni(s)-0.403 cd2+(aq)+2e−→cd(s)-0.76 zn2+(aq)+2e−→zn(s)a) what is the cathode half-reaction? b) what is the anode half-reaction? c) a single nickel-cadmium cell has a voltage of 1.30 v. based on the difference in the standard reduction potentials of cd2+ and zn2+, what voltage would you estimate a nickel-zinc battery will produce? d) would you expect the specific energy density of a nickel-zinc battery to be higher or lower than that of a nickel-cadmium battery?
