标准范围

试验部分在硫酸钠存在下用乙醇回流煮沸。过滤溶液，蒸发滤液，称量残渣。通过将残留物溶解在丙酮水溶液中，并用标准容量硝酸银溶液滴定，来测定存在的任何氯化钠。根据氯化钠含量校正残留物的质量。

A test portion is boiled under reflux with ethanol in the presence of sodium sulphate. The solution is filtrated, the filtrate evaporated, and the residue weighed. Any sodium chloride present is determined by dissolution of the residue in aqueous acetone and titration with a standard volumetric silver nitrate solution. The mass of the residue is corrected for the sodium chloride content.
