When H2S gas is passed into aqueous sulphur dioxide
A.a clear solution of H2SO4 is formed
B.SO2 is converted into a yellow precipitate of
C.H2S is converted into a yellow precipitate of
D.both SO2 and H2S are converted into a yellow✓ Correct
Explanation
With the passage of 2 H S gas into the aqueous sulfur dioxide, 2 H S changes its oxidation state from -2 to 0. Hence, it gets oxidized and produces elemental sulfur and cause the yellow turbidity 2 2 2 2 ( ) 3 2 H S SO aq S H O -> Thus, the correct option is (d)
