Answer 1

MnO₄²⁻ + C₂O₄²⁻ → Mn⁺² + CO₂  

a) Assign oxidation numbers for each atom in the equation. Oxidation number (also called oxidation state) is a measure of the degree of oxidation of an atom in a substance (see: Rules for assigning oxidation numbers).

(Mn⁺⁶O⁻²₄)²⁻ + (C⁺³₂O⁻²₄)²⁻ → Mn⁺² + C⁺⁴O⁻²₂  

Oxidation: (C⁺³₂O⁻²₄)²⁻ → 2C⁺⁴O⁻²₂ + 2e⁻ (C)

Reduction: (Mn⁺⁶O⁻²₄)²⁻ + 4e⁻ → Mn⁺² (Mn)

R:(Mn⁺⁶O⁻²₄)²⁻ + 4e⁻ + 8H⁺ → Mn⁺²

R:(Mn⁺⁶O⁻²₄)²⁻ + 4e⁻ + 8H⁺ → Mn⁺²  + 4H₂O  

O:(C⁺³₂O⁻²₄)²⁻ → 2C⁺⁴O⁻²₂ + 2e⁻                  [*2]

R:(Mn⁺⁶O⁻²₄)²⁻ + 4e⁻ + 8H⁺ → Mn⁺²  + 4H₂O                  

[*1

]

O: 2(C⁺³₂O⁻²₄)²⁻ → 4C⁺⁴O⁻²₂ + 4e⁻

R:(Mn⁺⁶O⁻²₄)²⁻ + 4e⁻ + 8H⁺ → Mn⁺²  + 4H₂O    

adding equations

2(C⁺³₂O⁻²₄)²⁻+(Mn⁺⁶O⁻²₄)²⁻ + 4e⁻ + 8H⁺ → 4C⁺⁴O⁻²₂ + 4e⁻ +Mn⁺²  + 4H₂O  

MnO₄²⁻ + 2C₂O₄²⁻ + 8H⁺ → Mn²⁺ + 4CO₂ + 4H₂O
