Which of the following reactions occur at the negative electrode if a 1 M NaCl (aq) solution is used as a plating solution? Select a balanced reduction half-reaction below for your answer. Hint - Na metal cannot be produced in aqueous solutions. Na+ + e- → Na (s) Cl2 + 2 e- → 2 Cl- (aq) H2O + e- → 1/2 H2 (g) + OH- (aq) H2O → H+ (aq) + OH- (aq) Na + e- → Na- (aq)
