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

The correct option is 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.
