1、精选优质文档-倾情为你奉上已知准确浓度的溶液。在滴定分析中常用作滴定剂。在其他的分析方法中用标准溶液绘制工作曲线或作计算标准。 配制方法有两种，一种是直接法，即准确称量基准物质，溶解后定容至一定体积；另一种是标定法，即先配制成近似需要的浓度，再用基准物质或用标准溶液来进行标定。 已知准确浓度的溶液，在容量分析中用作滴定剂，以滴定被测物质。 如果试剂符合基准物质的要求 (组成与化学式相符、纯度高、稳定)，可以直接配制标准溶液，即准确称出适量的基准物质，溶解后配制在一定体积的容量瓶内。可由下式计算应称取的基准物质的重量W：WV基准物质的摩尔质量。式中和V分别为所需配制的溶液的摩尔浓度和体积。利用上

2、式可计算出标准溶液的浓度。 如果试剂不符合基准物质的要求，则先配成近似于所需浓度的溶液，然后再用基准物质准确地测定其浓度，这个过程称为溶液的标定。Element元素Source, Purity, MatrixCat.
