Question

Sulphur and chlorine are oxidizing and reducing agents ?

Answer 1

Oxidizing agents are those compound which carry out oxidation of other substance either by providing oxygen or by removing hydrogen from other substance. Reducing Agents are those compounds which carry out reduction of other substance either by providing hydrogen, or by removing oxygen from the other substance.

For ex: H₂S + Cl₂ --> 2HCl + S

Here, H₂S gets oxidized to S(removal of H) in presence of Cl₂ it means Cl₂ is an oxidizing agent.

Cl₂ is reduced to HCl in presense of H₂S therefore S is reducing agent. (H is being added or removed so the oxidizing or reducing species is Cl or S).
