Question

Which of the following reactions depicts the oxidising property of SO2? (A) SO2 + H2O arrow H2SO3 (B) 2H2S + SO2 arrow 3S + 2H2O (C) Cl2 + SO2 arrow SO2 Cl2 (D) 2 MnO-4 + 5 SO2 + 2 H2O arrow 5 SO2-4 + 2 Mn2+ + 4 H+

2 H2S + SO2 arrow 3 S + 2 H2O Here SO2 acts as an oxidising agent and thus oxidises H2S to S.

Q. Which of the following reactions depicts the oxidising property of $S O_{2}$ ?

$S O_{2} + H_{2} O \to H_{2} S O_{3}$

$2 H_{2} S + S O_{2} \to 3 S + 2 H_{2} O$

$C l_{2} + S O_{2} \to S O_{2} C l_{2}$

$2 M n O_{4}^{-} + 5 S O_{2} + 2 H_{2} O \to 5 S O_{4}^{2 -} + 2 M n^{2 +} + 4 H^{+}$

$2 H_{2} S + S O_{2} \to 3 S + 2 H_{2} O$ Here $S O_{2}$ acts as an oxidising agent and thus oxidises $H_{2} S$ to $S$ .

Q. Which of the following reactions depicts the oxidising property of SO2​?

SO2​+H2​O→H2​SO3​

2H2​S+SO2​→3S+2H2​O

Cl2​+SO2​→SO2​Cl2​
