4 Principle

The chlorides, dissolved in water, are precipitated in an acidified medium by an excess of standard

solution of silver nitrate. The chloride concentration in the samples is quantified by potentiometric

determination. To detect the end point, the voltage between a reference electrode on the one hand and

the silver electrode or an ion selective electrode on the other hand, is tracked. This voltage depends on

the logarithm of the chloride ion activity. If it is plotted, in mV, on the ordinate and the silve
