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

We begin by writing the equation for the redox reaction.

2ClO²⁻ + 2H₂O₃ — > 3O₂ (g) + 2 Cl⁻ + 2H₂O

From the equation we can state the mole ratios.

ClO²⁻ : H₂O₃

1 : 1

Given that the moles ratio is 1 : 1

One mole of H₂O₃ is oxidized by one mole of ClO²⁻.

Answer 2

Answer:

We begin by writing the equation for the redox reaction.

2ClO²⁻ + 2H₂O₃ — > 3O₂ (g) + 2 Cl⁻ + 2H₂O

From the equation we can state the mole ratios.

ClO²⁻ : H₂O₃

1 : 1

Given that the moles ratio is 1 : 1

One mole of H₂O₃ is oxidized by one mole of ClO²⁻.
