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:W=ΜV·基准物质的摩尔质量。式中Μ和V分别为所需配制的溶液的摩尔浓度和体积.利用上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 Aluminum(铝) Antimony(锑) Source, Purity, Matrix Al metal, 99。999%, 2% HNO3 Al metal, 99。999%, 2% HCl Cat.
