For 1 mole of S₂O₃²⁻ 0.5 mole of S₂O₈²⁻ will be used.

<h3>What is a balanced Reaction ?</h3>

A reaction in which the number of atoms in reactants is equal to the number of atoms in the products is called a balanced reaction.

The reaction given in the question is

S₂O₈²⁻ + 2I⁻ ⇄ 2SO₄²⁻ + I₂

I₂ + 2S₂O₃²⁻ ⇄ 2I⁻ + S₄O₆²⁻

Adding the equation will give balance equation

S₂O₈²⁻ + 2I⁻ + 2S₂O₃²⁻ ⇄ 2SO₄²⁻ + 2I⁻ + S₄O₆²⁻

So x moles of S₂O₈²⁻ require 2x of S₂O₃²⁻

for 1 mole of S₂O₃²⁻ 0.5 mole of S₂O₈²⁻ will be used.
