Question
Using Electrochlorination to Clean Water
Aqueous hypochlorite ions are added to drinking water and swimming pools
to make the water safe for people to use. Electrochlorination uses an
electrolytic cell like the one below to make hypochlorite ions from chloride
ions in the water. Hydrogen gas is a byproduct.
Power
source
Clag) +2 OH (ag) → OC ag) + H2O@ + 2 e-
2 H* (mg + 2 e → Hz)
Which statements below are correct for the electrochlorination cell above?
1 The net reaction is spontaneous.
2 The net reaction is non-spontaneous.
3 Hypochlorite ions form at the anode.
4 Hypochlorite ions form at the cathode.
5 Hydrogen forms at the electrode connected to the negative side of the power source.
6 Hydrogen forms at the electrode connected to the positive side of the power source.
7 The cell produces electrical energy.
8 The cell uses electrical energy.
