of a solution containing  of impure sample of  reacts with  of  in presence of  as per the reaction:

Find the purity of  solution:

Canvas Classes · Accepted Answer

Strategy:
 In this redox titration, we use the stoichiometry of the balanced equation to relate the moles of  to . Purity is then calculated as the percentage of the calculated pure mass relative to the original sample mass.

Step 1: Identify the stoichiometric ratio
Balanced equation: .
Ratio: 2 moles  moles .

Step 2: Calculate moles of reactants
- Moles of 
- Moles of

Step 3: Calculate purity
Mass of pure
