Ca(OH)2 + HF → CaF + H(OH)2
This is an acid-base reaction (neutralization): Ca(OH)2 is a base, HF is an acid.
This is an oxidation-reduction (redox) reaction:
CaII + e- → CaI (reduction)
2 O-II - 1 e- → 2 O-3/2 (oxidation)
Ca(OH)2 is an oxidizing agent, Ca(OH)2 is a reducing agent.
Reactants:
- Ca(OH)2 – Calcium hydroxide
- HF – Fluorane
- Other names: Hydrofluoric acid , Hydrogen fluoride , Fluorhydric acid
