A determination by weight; e.g. in the older method of Cl−
ion determination, a weighed amount of sample is dissolved in water, AgNO3
solution added, AgCl
is precipitated, dried and weighed. From the known mass fraction of silver in AgCl
, the weights of the initial sample and that of the AgCl
precipitated, the percentage of chlorine in the sample can be calculated readily.
