Argentometric titration of chloride with dichlorofluoroscein as an adsorption indicator: A useful modification.

The addition of excess of ethyl alcohol renders more useful the argentometric titration of chloride with dichlorofluoroscein as adsorption indicator by improving the end-point, both when simple counter-ions are present and also when the presence of adsorbable and/or complexing counter-ions renders the normal technique inadequate.
