| 摘 要： | 本文研究了测定钡盐中钡含量的快速方法。该法是基于被测的钡离子与过量的铬酸钠标准溶液反应形成铬酸钡沉淀，剩余的铬酸根离子以溴甲酚绿-甲基红为混合指示剂，用盐酸标准溶液滴定，而间接测定钡的量。该法操作简便、快速，可应用于多种钡盐中钡的测定。

| Abstract: | In this paper, the quick method of determination barium content in bane salts was studied. The method is based on the fact that barium ion reacts with sodium chromate standard solution to form precipitation of barium chromate, then the residue sodium chromate can be titrated with hydrochloric acid standard solution and bromocresol green - methyl red as indicator, so the content of barium in baric salt was found out. The method is easy and quick in operation and is used in the determination of barium in many kinds of baric salts. |
