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. consider the following:
ni2+(aq)+2e- -> ni(s), e red = -0.23v cu2+(aq)+2e- -> cu(s), e red = +0.337v
what is the standard potential, e cell, for this galvanic cell? express your answer to four significant figures and include the appropriate units.
