# What is the ionization of a strong acid?

Example: Ionization of the strong acid $H C l$ is represented by the reaction
$H C l \left(a q\right) + {H}_{2} O \leftrightarrow {H}_{3} {O}^{+} \left(a q\right) + C {l}^{-} \left(a q\right)$
For strong acids, the equilibrium constant for this reaction lies strongly toward products (${K}_{a} > > 1$). For HCl, the value of ${K}_{a}$ is greater than ${10}^{6}$.
