All of the following are postulates of Arrhenius theory of ionization except
Correct answer: B. ionization is a reversible process
- A. electrolytes ionize in water to produce cations and anions
- B. ionization is a reversible process
- C. electrical conductivity of a solution of an electrolyte depends on the extent to which the electrolyte ionizes in the solution
- D. strong electrolyte ionize to a greater extent in water
Explanation
The Arrhenius theory of ionization does not specifically address the reversibility of the ionization process. The theory primarily focuses on the ionization of electrolytes in water, leading to the production of ions. It describes the dissociation of electrolytes into ions in aqueous solutions, contributing to the electrical conductivity of the solution.

About Acids, Bases and Salts
Acid and base behaviour is explained through the Bronsted-Lowry transfer of protons and the Lewis donation or acceptance of electron pairs. The topic includes pH, pOH, ionisation and water equilibrium, plus salt formation and hydrolysis, where a salt solution may become acidic, basic or neutral.
