Usanovich Concept of Acid-Base
In 1938, Russian physical chemist Mikhail Usanovich developed a general theory of acids and bases. According to this concept, “An acid is any species capable of giving cations, combining with anions or electrons or neutralizing a base to give a salt and a base is any species capable of giving up anions or electrons, combining with cation or neutralizing an acid to form salt.”
- Usanovich Acids: SO3, Cl2, etc.
- Usanovich Bases: Na2O, Na, etc.
This concept is useful in classifying all types of acids and bases, as well as it also considers the oxidation-reduction process.
Examples of Usanovich Acid-Base Reactions
Na2O (base) + SO3(acid) → 2 Na+ + SO42− (O2−anion exchanged)
2Na (base) + Cl2 (acid) → 2Na+ + 2Cl−(2 electrons exchanged)
3(NH4)2S (base) + Sb2S5 (acid) → 6NH4+ + 2SbS43- (S2- anion exchanged)
