Na3SbO4 + 4 Mg + 11 HCl → SbH3 + 4 MgCl2 + 3 NaCl + 4 H2O
This is an oxidation-reduction (redox) reaction:
4 Mg0 - 8 e- → 4 MgII (oxidation)
SbV + 8 e- → Sb-III (reduction)
Mg is a reducing agent, Na3SbO4 is an oxidizing agent.
Reactants:
- Na3SbO4
- Mg
- 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.]
