The active ingredient formed by aspirin in the body is salicylic acid, C H OH(CO₂H). The carboxyl group (-CO,H) acts as a weak acid. The phenol group (an OH group bonded to an aromatic ring) also acts as an acid but a much weaker acid. What are all of the ionic and molecular species present in a 0.001-M aqueous solution of C H₂OH(CO₂H) in order of descending concentration?
