Arrhenius & bronsted Lowery definitions have greater similarity in
Correct answer: B. Acid definitions
- A. Base definitions
- B. Acid definitions
- C. Both of these
- D. None of these
Explanation
The correct answer is Acid definitions. Both the Arrhenius and Bronsted-Lowry definitions agree that acids are substances that increase the concentration of hydrogen ions (H⁺) in solution. The Arrhenius definition specifies that acids ionize in water to produce H⁺ ions, while the Bronsted-Lowry definition expands on this by describing acids as proton donors. However, the definitions of bases differ: Arrhenius bases yield hydroxide ions (OH⁻) in solution, whereas Bronsted-Lowry bases accept protons (H⁺). Therefore, only the acid definitions show greater similarity between the two theories.

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.
