As per Bronsted-Lowry concept, acid is defined as:
Show Hint
- Electron pair acceptor
- Any substance/molecule that can accept a proton
- Any substance/molecule that can donate a proton
- Electron pair donor
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Bronsted-Lowry concept. The Bronsted-Lowry theory defines acids and bases based on proton (H\(^+\)) transfer: - Acid: A substance that donates a proton (H\(^+\)) in a reaction. - Base: A substance that accepts a proton (H\(^+\)).
Step 2: Explanation of correct answer. According to the Bronsted-Lowry concept, an acid is any molecule or ion that donates a proton (H\(^+\)), which makes option (C) correct.
Step 3: Why other options are incorrect. - (A) Electron pair acceptor: This definition aligns with Lewis acids, not Bronsted-Lowry acids.
- (B) Any substance/molecule that can accept a proton: This defines a Bronsted-Lowry base, not an acid.
- (D) Electron pair donor: This describes Lewis bases, not acids.
