Solution

H₂S + Cl₂ $\to$ S + 2HCl

1) H₂S is oxidised to S by losing hydrogen atoms.
2) Cl₂ is reduced to HCl by gaining hydrogen atoms.
3) The substance which gets oxidised is called reducing agent. Hence H₂S is reducing agent.
4) The substance which gets reduced is called oxidising agent. Hence Cl₂ is oxidising agent.
