一、概述 1.特点和主要方法 容量分析法又称滴定分析法。方法是基于将一种已知准确浓度的试剂溶液(标准溶液)滴加到被测物质的溶液中,直至所加试剂与被测物质按化学计算定量反应为止。然后根据试剂溶液的浓度和用量,计算被测物质的含量。 容量分析通常用于测定常量组分,即被测组分的含量一般在1％以上,有时也可测 First, an overview 1. Features and main methods Volumetric analysis, also known as titration analysis. The method is based on the dropwise addition of a reagent solution (standard solution) of known concentration to the solution of the test substance until the stoichiometric reaction between the reagent and the test substance is made. Then according to the reagent solution concentration and dosage, calculate the content of the test substance. Volumetric analysis is usually used to determine the constants, that is, the content of the tested components is generally above 1%, sometimes it can be measured
