USANOVICH CONCEPT OF ACID AND BASE
Usanovish in 1939 proposed a concept of acid and base and it was the most comprehensive concept.
Acids:
According to this concept, an acid is capable of
- combining with electrons
- combining with anions
- giving up cations
An acid is a cation, a cation donor, an electron pair acceptor, or an oxidant.
Bases:
According to this concept, a base is capable of
- giving up anions
- giving up electrons
- combining with cations
An base is an anion, a cation acceptor, an electron-pair donor
For example:
\[SO_{3}\; +\; Na_{2}O\; \rightarrow Na_{2}SO_{4}\]
In the above example, Na2O gives an oxide ion so it is an acid and SO3 accepts this oxide ion so it is a base.
