Question

The strength of an acid depends on its tendency to:

• A. Accept protons
• B. Donate protons
• C. Accept Electrons
• D. Donate electrons

Answer 1

Answer: (B)

Donate protons

Acids are defined by their ability to donate protons. Mineral acids like ${\text{H}}_2{\text{SO}}_4$ donate protons easily, so, they are strong acids. Organic acids like ${\text{CH}}_3\text{COOH}$ do not donate their protons so easily, hence they are weak acids.
