Solvent-system conception of acids and bases

The electrolytic conception of acids and bases can be extended to other ionizing solvents by means of the following definitions  

An acid is a compound that ionizes to give the cation natural to the solvent. 

The ions natural to a solvent are those produced in its self-ionization. For some of the more important ionizing solvents, these are as follows. 

NH4CI is an acid in liquid ammonia, KNH2 is a base, KHSO4 is a base in 100% sulfuric acid, etc.

In 1905, Franklin introduced the solvent system concept of acids and bases. This theory recognizes the ionization of a solvent to give a cation and an anion for example, 2H2O + OH" or 2NH3 NH4 + NH2". An acid is defined as a...
