Question

6. Write the reaction of so2 with (a) FeCl, (b) KMnO4​

Answer 1

Explanation:

a) FeCl2

b) SO2 gas reacts with acidified KMnO4 solution and pink colour of solution becomes colourless.

Answer 2

Answer:

(a)

H2O + SO2+ FeCl3 - H2SO4 + HCI + FeCl

H2O + H2S + FeCl3 H2SO4 + HCI + FeCl

SO2+ FeCl3 + HOH - H2SO4 + HCI + FeCl

(b) SO₂ gas reacts with acidified KMnO4 solution and pink colour of solution becomes colourless.

2KMnO4 + 3H₂SO4 → K₂SO4 + 2MnSO4 + 3H₂O + 5[0] SO₂ + [O] → SO3 ]× 5 H₂O+SO3 → H₂SO4 ] × 5

2KMnO4 + 2H₂O +5SO2 → K2SO4

+2MnSO4 + 2H₂SO4
