Hydrohalic acids are binary compounds formed by hydrogen ( H ) and a non-metallic element ( X ), may be a (allogenic or chalcogen.
The hydrohalic acids belong to the group of Inorganic Acid .
Only the Classical Nomenclature is used to name these acids:
- The acid (HX) is written and then indicated to be in aqueous solution (aq) or (ac).
- HF (aq) (Hydrofluoric acid)
- HBr (aq) (Hydrobromic acid)
- HI (aq) (Hydrochloric acid)
- HCl (aq) (Hydrochloric acid)
- H 2 S (aq) (Hydrogen sulfide)
- H 2 Se (aq) (Selenhydric acid)
- H 2 Te (aq) (Hydrogen telluride ACID)
- Hydrocyanic acid ( HCN ) produces the cyanide anion ( CN – )
Reactions hydrohalic acids: The hydrohalic acids react with metals to form salts Binary:
- HCl + Mg ? MgCl + 1/2 H 2
- HCl + Na ? NaCl + 1/2 H 2
