本文介绍采用毫克当量倒数为当量浓度的标准溶液,可大大简化分析结果的计算。如容量分析的计算式为:X=V×N×K/G (1)X=V×N×K/D×W (2)式中 X—计算结果;N——标准溶液当量浓度;V——消耗标准溶液的体积(毫升);K——被测物质毫克当量数(或换算成计算结果的系数);G——样品重量(克),D——样品比重;W——样品体积(毫升)。如使上式中N×K=1,N×K/W=1,或,N×K/W×D=1(D变化可忽略不计),则式(1)可简化为X=V/G;式(2)可简化为为X=V/G 或X=V。
This article describes the use of equivalent standard milligrams equivalent concentration of the standard solution can greatly simplify the calculation of the analysis results. If the capacity analysis of the formula is: X = V × N × K / G (1) X = V × N × K / D × W (2) where X- calculation results; N-- standard solution equivalent concentration; V - the volume of standard solution consumed in milliliters; K - the number of milligram equivalents (or the coefficient converted to the calculated result) of the test substance; G - the weight of the sample in grams, D - the weight of the sample; W - the volume of the sample (Ml). (1) can be simplified to X = V / V if N × K = 1, N × K / W = 1, or N × K / W × D = 1 in the above equation. G; Formula (2) can be simplified as X = V / G or X = V.
