Write a balanced half equation for the following couple: ClO2-(aq)| Cl-(aq) (basic)
◦ ClO2-(aq) + 2 H2O(l) + 4 e-→ Cl-(aq) + 4 OH-(aq)
◦ ClO2-(aq) + 4 H+(aq) + 4 e-→ Cl-(aq) + 2 H2O(l)
◦ ClO2-(aq) + H2O(l) + e-→ Cl-(aq) + OH-(aq)
◦ ClO2-(aq) + H+(aq) + e-→ Cl-(aq) + H2O(l)
◦ ClO2-(aq) + 4 H2O(l) + 8 e-→ Cl-(aq) + 4 OH-(aq)
