Ca(ClO2)2 + 8 HCl → CaCl2 + 4 Cl2 + 4 H2O
This is an oxidation-reduction (redox) reaction:
6 Cl-I - 6 e- → 6 Cl0 (oxidation)
2 ClIII + 6 e- → 2 Cl0 (reduction)
HCl is a reducing agent, Ca(ClO2)2 is an oxidizing agent (synproportionation (comproportionation)).
Reactants:
- Ca(ClO2)2
- 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.]
