Worksheet: Classifying Acids and Bases Based on Dissociation Constants
In this worksheet, we will practice classifying acids and bases as weak or strong based on their dissociation constants.
The relative acid strengths of and can be determined by comparing their acid and base dissociation constants, and . has a of and , the conjugate base of , has a of . Given that the self-ionization constant of water is , which compound is the stronger acid?
- AMore information is needed.
- B is the stronger acid.
- C is the stronger acid.
- D and are equally strong acids.
The active ingredient formed by aspirin in the body is salicylic acid, . The carboxyl group acts as a weak acid. The phenol group (an group bonded to an aromatic ring) also acts as an acid, but a much weaker acid.
Which one of the following is false for a 0.001 M aqueous solution of salicylic acid?
