Abstract:

Potentiometry, a polarisation end-point method and differential electrolytic potentiometry have been investigated for sensitivity of endpoint indication for the routine argentometric determination of up to 50 micrograms of chloride ion. A small volume and high acetone concentration were necessary for optimum indication by the three methods. Potentiometry and differential electrolytic potentiometry required ca 30 min for a titration polarisation end-point required ca 10 min. End-points were clearly indicated without plotting curves to 0.07 microgram with 0.004 N silver nitrate as titrant. Author
