Ca(ClO)2 + 4 KI + 4 HCl → 2 I2 + CaCl2 + 4 KCl + 2 H2O
This is an oxidation-reduction (redox) reaction:
2 ClI + 4 e- → 2 Cl-I (reduction)
4 I-I - 4 e- → 4 I0 (oxidation)
Ca(ClO)2 is an oxidizing agent, KI is a reducing agent.
Reactants:
- Ca(ClO)2
- KI
- 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.]
