本文通过试验得出 ,配制确定浓度易水解无机盐 Sn Cl2 水溶液和 Bi Cl3水溶液时所需盐酸的最低量 ,可使盐酸用量比文献所加入量分别节约 88%和 5 1 % .该配制方法具有推广价值 .
In this paper, we conclude that the minimum amount of hydrochloric acid required to determine the concentrations of the readily hydrolyzable inorganic salts Sn Cl2 and Bi Cl3 aqueous solutions can save 88% and 51%, respectively, of the amount of hydrochloric acid used in the literature. The preparation method has Promote value.
