16. The number of moles of KMnO4 that will beneeded to react with one

1.	16. The number of moles of KMnO4 that will beneeded to react with one mole of sulphiteion in acidic solution is ICBSE AIPMT 2007(a) 4/5 (b) 2/5 (c) 1(d) 3/5
Answer» The reaction will be 2KMnO4 + 5 H2SO3 --> K2SO4 +2 MnSO4 +2 H2SO4 + 3H2O As 5 mole of sulphite reacts with 2 mole of KMnO4 Then 1 mole will react with 2/5 mole of KMnO4 in what way you write the reaction? thaku

Answer»

The reaction will be

2KMnO4 + 5 H2SO3 --> K2SO4 +2 MnSO4 +2 H2SO4 + 3H2O

As 5 mole of sulphite reacts with 2 mole of KMnO4

Then 1 mole will react with 2/5 mole of KMnO4

in what way you write the reaction?
