3 ReCl5 + 8 H2O → HReO4 + 2 ReO2 + 15 HCl
This is an oxidation-reduction (redox) reaction:
ReV - 2 e- → ReVII (oxidation)
2 ReV + 2 e- → 2 ReIV (reduction)
ReCl5 is both an oxidizing and a reducing agent (disproportionation (dismutation)).
Reactants:

- 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.]
