The equation that correctly represents the dissociation of a strong acid in water is as follows: HCl → H+ + Cl−
Acid dissociation is the process by which an acid breaks up into it's constituent ions in an aqueous solution.
Acids are known to contain hydrogen ions (H+), hence, dissociate into H+ and an anion.
A strong acid like HCl dissociates completely in an aqueous solution while a weak acid does not dissociate completely.
According to this question, hydrogen chloride (HCl) is said to dissociate into hydrogen ion (H+) and chloride (Cl-) according to the following expression:
HCl → H+ + Cl−
