1.
Oxidizing agent : Cl₂
reducing agent : Cl₂
Oxidation half reaction :
Cl₂(g) + 4OH⁻(g) → 2ClO⁻(aq) + 2H₂O(l) + 2e⁻
Reduction half reaction :
Cl₂(g) + 2e⁻ → 2Cl⁻(g)
====
2.
Oxidizing agent : H₂O
Reducing agent : Ca
Oxidation half reaction :
Ca(s) → Ca²⁺(aq) + 2e⁻
Reduction half reaction :
2H₂O(l) + 2e⁻ → 2OH⁻(aq) + H₂(g)
Oxidizing agent : Cl₂
reducing agent : Cl₂
Oxidation half reaction :
Cl₂(g) + 4OH⁻(g) → 2ClO⁻(aq) + 2H₂O(l) + 2e⁻
Reduction half reaction :
Cl₂(g) + 2e⁻ → 2Cl⁻(g)
