Question

In alkaline medium, clo2 oxidises h2o2 to o2 and is itself reduced to cl−. how many moles of h2o2 are oxidised by 1mole of clo2?

Answer 1

Equations :

ClO²⁻ (aq) + H₂O₂ (l) — > Cl⁻ + O₂ (g) + H₂O (l)

The mole ratio is 1 : 1

Since the mole ratio is 1 :1 ;

I) Moles of ClO²⁻ = moles of H₂O₂

We therefore conclude that :

The moles of H₂O₂ that will be oxidized by 1 mole of ClO²⁻ is 1 mole.
