滴定溶液

This test is a measure of the unsaturated linkages in a fat and is determined by reacting the fat with a solution of iodine monochloride in a mixture of acetic acid and CCU, liberating excess iodine with KI, and titrating with Na2S203.

这个试验是不饱和键的测量，它由脂肪与一氯化碘在乙酸与CCU的混合物的溶液反应进行测量，用KI除多余的碘，用硫代硫酸钠滴定。

Place in a 250 ml conical flask fitted with a ground-glass stopper, 10.0 ml of the solution, 15 ml of water R, 5 ml of hydrochloric acid R and 4 g of potassium iodide R, close the flask, allow to stand in the dark for 15 min and add 100 ml of water R.

After the solution was kept in the dark for five minutes,chloroform was added into it to adsorb selenium formed by previous reaction,then iodine separated out was determined by sodium hyposulfite titration using starch as the indicator,at last the content of selenium dioxide in the sample was foun.

在溶有二氧化硒的0.4～0.5mol/L盐酸介质中，加入过量的碘化钾，于暗处放置5min后，加入三氧甲烷吸附反应生成的硒，以淀粉为指示剂，用硫代硫酸钠标准溶液滴定析出的碘，测得二氧化硒的含量。

This method is fast,accurate,simple and is used to the routine check of the metallic iron in sponge iron with satisfactory result.

介绍了用三氯化铁-重铬酸钾容量法测定海绵铁中金属铁的方法，试样用三氯化铁溶液选择性地使金属铁溶解，过滤分离不溶物，移取部分滤液，用重铬酸钾容量法直接滴定，方法快速准确，操作简便，用于海绵铁中金属铁的日常检测，可获得满意结果。

The principle of the method is for NaOH solution to absorb CO 2 released by soil breath,then for acid to titrate the remaining NaOH to calculate released CO 2 amount.

方法原理是用NaOH溶液吸收土壤呼吸释放出的CO2，然后再用酸滴定剩余的NaOH，从而计算出CO2释放量。

It is very useful in the buffering region of the titration of a weak acid.

它在弱酸滴定的缓冲区是很有用的。pKa在某溶液离子强度下是-logKa。

Titrimetry is a quantitative method using solution chemistry to determine the concentration of analyte.

滴定法是利用溶液化学来测定分析物浓度的定量分析方法。

The labor cost to manufacture a given part or to perform a service depends on the number of work hours and the wage rate.

其电离酸溶液开始的pH值在很大程度上取决于电离度，其滴定曲线也非常清晰。

In medium of mixed sulphuric acid and phosphoric acid, with N-phenylated anthranilic acid as a tracer agent, the standard solution of ammonium ferrous sulphate is used to titrate chromium.

试样以硝酸、氢氟酸溶解，加高氯酸冒烟驱除硅和氟，并将铬氧化为六价，在硫磷混合酸介质中，以N-苯代邻氨基苯甲酸为指示剂，用硫酸亚铁铵标准溶液滴定铬。
