摘要

本文简述了十水和无水硫酸钠相转变点降低实验的原理、方法和装置。在实验中为防止水玻璃水解

我们向水玻璃溶液中加入NaOH溶液

之后通过外推NaOH浓度到零以消除NaOH对硅酸根聚合度的影响

从而测得不同模数水玻璃溶液中硅酸根离子的平均聚合度.得到的聚合度数据与光散射法和硅钼酸反应法测得的数据做了对比

并讨论了影响实验准确度的主要因素.

Abstract

The principle

the method and the apparatus for the experiment on the phase- change-point lowering between decahydrate and anhydrous sodium sulfates are briefly described in this paper. In the experiment

sodium hydroxides were put into the water glass solutins to provent water glass from hydrolysis. Then the average degrees of polymerization of silicate ions in the water glass with different modules have been determined by extrapolating the NaOH concentration to zero so as to eliminate the influence of NaoH on the degrees of polymeriz- ation. The data obtained are compared with those obtained from the light- scattering and the silicomolybdic acid reaction. The important factors which affect the experimental accuracy have also been discussed.
