Choose at least one answer. should be 3-4 right answers a. 2Cl- ? 2Cl2(g) + 2e- (anode) b. 2H2O(l) ? O2(g) + 4H+(aq) + 4e- (anode) c. 2SO42-(aq) ? S2O82-(aq) + 2e- (anode) d. Ni(s) ? Ni2+(aq) + 2e- (anode) e. Ni2+(aq) + 2e- ? Ni(s) (cathode) f. Mg2+(aq) + 2e- ? Mg(s) (cathode) g. 2H2O (l) + 2e-? H2(g) + 2OH - (aq) (cathode) h. No net reaction. However, metal is transfer from the anode to the cathode. i. Cl2(g) j. H2(g) k. O2(g) l. Mg(s) m. Ni(s) n. S2O82-(aq) o. OH -(aq)
