Question

the number of moles of kmno4 that will be needed to react with one mole of sulphite ions in acidic solution is

Answer 1

2 KMnO↓4 + 5 H↓2 SO↓3 → K ↓2SO↓4 + 2 MnSO↓4 + 2 H↓2 SO↓4 + 3 H↓2 O 

2 moles of KMnO↓3 react with 5 moles of sulphite ion in acidic solution.Thus, 2/5 moles of KMnO↓4 will react with 1 mole of sulphite ion.
