Ans : H2S is oxidized because of a more electronegative element, Chlorine, and it is added to hydrogen (or more electropositive element hydrogen has been removed from S). Chlorine is reduced due to the addition of hydrogen.
In the reactions below, identify the following species undergoing oxidation and Reduction? H2S (g) + Cl2 (g) →2HCl (g) + S (S)
