The balance chemical equation is :
From the equation it is clear that Moles of MnO4– require to oxidise 5 moles of SO3– – are 2
Moles of MnO4– require to oxidise 1 mole of SO3– – are 2/5.
Moles of MnO4– require to oxidise 1 mole of SO3– – are 2/5.

Acidic solution means the medium in which the reaction takes place is acidic. The reaction between KMnO4 and sulphite ion in acidic medium can be represented as follows:
5 SO32- + 2 MnO4- + 6 H+ → 5 SO42- + 2 Mn2+ + 3 H2O
From the balanced equation, it is clear that 2 moles of KMnO4 are required to react with 5 moles of sulphite ion in acidic solution. Therefore, the number of moles of KMnO4 that will be needed to react with one mole of sulphite ion in acidic solution is:
2 moles KMnO4 / 5 moles SO32- = 0.4 moles KMnO4 / 1 mole SO32-
Therefore, the correct answer is option B, 2/5.
5 SO32- + 2 MnO4- + 6 H+ → 5 SO42- + 2 Mn2+ + 3 H2O
From the balanced equation, it is clear that 2 moles of KMnO4 are required to react with 5 moles of sulphite ion in acidic solution. Therefore, the number of moles of KMnO4 that will be needed to react with one mole of sulphite ion in acidic solution is:
2 moles KMnO4 / 5 moles SO32- = 0.4 moles KMnO4 / 1 mole SO32-
Therefore, the correct answer is option B, 2/5.
