Concept:Acid strength is fundamentally defined by the extent to which an acid dissociates into protons (\( \text{H}^+ \)) in aqueous solution.
Solution:- Sulfuric acid (a mineral acid) ionizes almost completely in water, releasing massive amounts of \( \text{H}^+ \).
- Acetic acid (an organic acid) exists in a tight equilibrium where only a tiny fraction (less than 1%) of the molecules dissociate.
- Because it has a much less degree of ionization, it provides far fewer protons, categorizing it scientifically as a weak acid.
Why other options are incorrect:Thermal stability and inductive effects do not serve as the fundamental thermodynamic definition of acid strength in solvent, whereas the degree of ionization (\( \alpha \)) directly does.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
