Ca(ClO3)2 (aq) + 12 HCl (aq) → CaCl2 (aq) + 6 Cl2 (g) + 6 H2O (l)
This is an oxidation-reduction (redox) reaction:
10 Cl-I - 10 e- → 10 Cl0 (oxidation)
2 ClV + 10 e- → 2 Cl0 (reduction)
HCl is a reducing agent, Ca(ClO3)2 is an oxidizing agent (synproportionation (comproportionation)).
This is a gas evolution reaction, Cl2 is the formed gas.
Reactants:
- Ca(ClO3)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.]
