When SO₂ gas is passed through saturated solution of H₂S, the following reaction occurs:SO₂ + 2H₂S -----> 2H₂O + 3S In this reaction, which substance is oxidised and which one is reduced?

Academic Chemistry NCERT Class 10

$SO_{2} \ +\ 2H_{2} S\rightarrow \ 2H_{2} O\ +\ 3S\ $

In the above reaction, SO₂ is reduced to S, as it loses oxygen.

H₂S is oxidised to H₂O, as it gains oxygen.
