2 CaClO2 + 8 HCl → 2 CaCl2 + 3 Cl2 + 4 H2O
This is an oxidation-reduction (redox) reaction:
2 ClII + 4 e- → 2 Cl0 (reduction)
4 Cl-I - 4 e- → 4 Cl0 (oxidation)
CaClO2 is an oxidizing agent, HCl is a reducing agent (synproportionation (comproportionation)).
Reactants:
- CaClO2
- HCl – Chlorane , Hydrogen chloride
- Other names: Hydrochloric acid , M , Uriatic acid
- Appearance: Colorless, transparent liquid, fumes in air if concentrated ; Colorless gas ; Colourless compressed liquefied gas with pungent odour ; Colorless to slightly yellow gas with a pungent, irritating odor. [Note: Shipped as a liquefied compressed gas.]
