Monoprotic Acid
An acid that can donate only one proton per molecule.
Formula / equation
HA ⇌ H⁺ + A⁻
Unit
mol/L
In depth
Monoprotic acids give simple 1:1 stoichiometry in neutralisation, so their titration curves show a single equivalence point and their molarity equals their normality. Most common laboratory and organic acids belong to this class.
Examples in the real world
Hydrochloric acid, nitric acid, ethanoic acid and benzoic acid.
