When HOCl is added to water, it dissociates to form hydrogen ions, H*, and hypochlorite ions, OCI. HOCl is an effective pool treatment because the oxygen in the HOCI molecule destroys bacteria, algae, and other substances. This uses up the HOCl. Describe this stress at the molecular level, and explain the effect the stress has on the HOCI equilibrium in terms of Le Châtelier's principle.
