Which of the following can be used as a solvent to distinguish between the K values of strong acids?
Correct answer: C. Aprotic solvent
- A. Protogenic solvent
- B. Protophilic solvent
- C. Aprotic solvent
- D. Organic solvent
Explanation
The correct answer is Option C: Aprotic solvent. Aprotic solvents are ideal for differentiating the K values of strong acids because they do not participate in proton transfer reactions. This allows for a clearer comparison of the acids' dissociation constants without interference from the solvent.Option A, protogenic solvents, donate protons, which can interfere with measuring the ionization of strong acids.Option B, protophilic solvents, can accept protons, potentially altering the acid's dissociation behavior.Option D, organic solvents, encompass a broad range of chemical properties, and not all are suitable for distinguishing strong acids' K values specifically.

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.
