Monoprotic acids

Definition

Monoprotic acids are acids that can donate only one proton (hydrogen ion) per molecule in an aqueous solution. Examples include hydrochloric acid (HCl) and acetic acid (CH3COOH).

5 Must Know Facts For Your Next Test

1. Monoprotic acids have a single dissociation step, represented by the equation HA → H+ + A-.
2. The pH of a monoprotic acid solution can be calculated using the concentration of the hydrogen ions produced.
3. Common monoprotic acids include hydrochloric acid, nitric acid, and acetic acid.
4. The strength of a monoprotic acid is determined by its dissociation constant (Ka).
5. Monoprotic acids play a crucial role in titration experiments to determine the concentration of basic solutions.
