The degree of ionization of a weak acid ________
I. varies with the concentration of the acid.
II. depends on which weak acid it is.
III. is 100%.
IV. is greater than 50% but less than 100%.

Question

Quizplus · Accepted Answer

The degree of ionization of a weak acid varies with its concentration (the more diluted the acid, the higher the degree of ionization) and depends on the nature of the acid itself (different weak acids have different ionization constants). It is not 100% nor is it typically greater than 50% but less than 100%, as weak acids do not fully ionize in solution.
