Part a describe the electrodes in this nickel-copper galvanic cell. drag the appropriate items to their respective bins. view available hint(s) nickel copper standard reduction potentials for nickel(ii) and copper(ii) the standard reduction potential for a substance indicates how readily that substance gains electrons relative to other substances at standard conditions. the more positive the reduction potential, the more easily the substance gains electrons. consider the following: ni2+(aq)+2e−→ni(s),cu2+(aq)+2e−→cu( s), e∘red=−0.230 v e∘red=+0.337 v part b what is the standard potential, e∘cell, for this galvanic cell? use the given standard reduction potentials in your calculation as appropriate.
