Question
What reactions occur during the electrolysis of aqueous Nal between Pt electrodes?
& of Na | Nat = -2.71 V
E of Pt | 12, 1 = 0.53 V
E
of Pt | H₂O, H₂, OH = -0.83 V
E of Pt | H₂O, O2, H+ = 1.23 V
H₂(g) evolves at the cathode, O2(g) evolves at the anode
Na(s) deposits at the cathode, 12(s) deposits at the anode
H₂(g) evolves at the cathode, 12(s) deposits at the anode
Na(s) deposits at the cathode, O2(g) evolves at the anode
