The names of acid salts are formed as follows: the name of the metal +

hydrogen (dihydrogen), if an anion of acid salt contains one (two) atoms

of Hydrogen, and the name of the anion

Acid salts can form only polybasic acids.

Nomenclature of acid salts

КНСO 3 - potassium hydrogen carbonate;

Nа 2НРО 4 - sodium hydrogen orthophosphat,

NаН 2РО 4 –sodium dihydrogen orthophosphat;

Fe(HSO 4) 3 - ferrum (III) hydrogen sulfate;

Alkali salts are products of incomplete neutralization polyacidic bases by

acids, or the interaction of neutral salt with the base alkali one:
Fe(OH) 3 + HCl = Fe(OH) 2Cl + H 2O,

Fe(OH) 3 + 2 HCl = (FeOH)Cl 2 + 2H 2O,
CoCl 2 + NaOH = (CoOH)Cl + NaCl.

The alkali salts can be formed only by a multi-acid base.

Nomenclature of alkali salts

The names of the main salts are formed as follows: the name of the metal

cation adding the word “hydroxo’ if the basic salt contains one group -

OH, and “dihydroxone” if there are two groups, and a name of an anion

AlOH(NO 3) 2 - Aluminium hydroxide nitrate,

Al(OH) 2NO 3 – Aluminium hydroxynitrate;

(FeOH)SО 4 - ferrum (III) hydroxo sulfate,

[Fe(OH) 2] 2SO 4 - ferrum (III) dihydroxosulphate.
