What products will be formed at the cathode and anode with the following entities
H20(l), K^+(aq), I^-(aq), C(s)
At the cathode:
- H2O(l) will be reduced to H2(g)
- K+(aq) will not be reduced because it is a spectator ion and does not participate in the redox reaction
- I-(aq) will also not be reduced because it is a spectator ion and does not participate in the redox reaction
- C(s) will not be reduced because it is a solid and does not participate in the redox reaction
At the anode:
- H2O(l) will be oxidized to O2(g)
- K+(aq) will be oxidized to K(g) as it forms a stable monatomic cation
- I-(aq) will not be oxidized because it is a spectator ion and does not participate in the redox reaction
- C(s) will not be oxidized because it is a solid and does not participate in the redox reaction
