How can you prepare Cl2 from HCI and HCI from Cl2?

Answer

(i) Cl2 from HCl: HCl can be oxidised to chlorine by the number of oxidising agent for example
By the action of any oxidising agent (whose oxidation potential is greater than Cl2) on HCl
MnO2 + 4HCl → MnCl2 + 2H2O + Cl2
2KMnO4 + 16HCl → 2KCl + MnCl2 + 8H2O + 5Cl2

(ii) HCl from Cl2: By the direct combination of elements i.e. hydrogen and chlorine in presence of sunlight.

H2 + Cl2→2HCl
