Strong base give leveling effect in
Correct answer: B. Protogenic solvent
- A. Protophilic solvent
- B. Protogenic solvent
- C. Aprotic solvent
- D. Organic solvent
Explanation
The leveling effect is the phenomenon where strong acids or bases appear to have the same strength in a particular solvent due to ionization. In a protogenic solvent, which is capable of donating protons, strong bases are neutralized by proton donation, resulting in a leveling effect. This means that all strong bases will appear to have the same strength as the strongest base that can exist in that solvent. Conversely, protophilic solvents accept protons, and aprotic solvents neither donate nor accept protons, making them unsuitable for providing a leveling effect. Organic solvents vary in their properties and are not defined specifically by their proton donating capabilities.

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.
