When H₂S gas is passed into aqueous sulphur dioxide

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)
