Complete and partial ionisation

Complete and partial ionisation

Ionisation is the process in which neutral acid particles form ions in water. A strong acid is completely ionised in aqueous solution, so nearly all its molecules split into hydrogen ions and negative ions. For a monoprotic acid with the formula HA\text{HA}HA, each acid particle that ionises produces one H+\text{H}^{+}H+ ion and one A−\text{A}^{-}A− ion, so the numbers of hydrogen ions and negative ions produced are equal.
