Options

  1. A2H⁺ ions reduced to H₂(g) at the cathode; 2H₂O(l) oxidized to O₂(g) and 4H⁺ ions at the anode.
  2. B2H⁺ ions reduced to H₂(g) at the cathode; 2H⁺ ions oxidized to O₂(g) and 2H₂O(l) at the anode.
  3. CCu²⁺ ions reduced to Cu(s) at the cathode; Cl⁻ ions oxidized to Cl₂(g) at the anode.
  4. DAg⁺ ions reduced to Ag(s) at the cathode; OH⁻ ions oxidized to O₂(g) and H₂O(l) at the anode.
