常用(yong)的(de)(de)載冷(leng)劑是水，但只能用(yong)于(yu)高(gao)于(yu)0℃的(de)(de)條件。當要求低于(yu)0℃時，一般采用(yong)鹽水，三門(men)峽二水粉氯化(hua)(hua)鈣，如氯化(hua)(hua)鈉(na)或氯化(hua)(hua)鈣鹽水溶液(ye)(ye)(ye)。鹽水溶液(ye)(ye)(ye)是鹽和水的(de)(de)溶液(ye)(ye)(ye)，它的(de)(de)性質取決于(yu)溶液(ye)(ye)(ye)中鹽的(de)(de)濃度(du)。

常用的兩種檢(jian)測液體中氯(lv)化鈣的含量，詳情如下：

一、化學方法：

1.加入過量碳酸(suan)鈉溶液，生(sheng)成碳酸(suan)鈣(gai)(gai)沉淀，然后洗滌干(gan)燥沉淀，稱量碳酸(suan)鈣(gai)(gai)的(de)(de)質(zhi)量，冷凍鹽水(shui)二水(shui)粉氯化(hua)(hua)鈣(gai)(gai)，計(ji)算物(wu)質(zhi)的(de)(de)量，就是氯化(hua)(hua)鈣(gai)(gai)的(de)(de)物(wu)質(zhi)的(de)(de)量，然后計(ji)算氯化(hua)(hua)鈣(gai)(gai)的(de)(de)質(zhi)量。

2.采用中EDTA法(fa)進行(xing)標定(ding)比較準確可(ke)靠。

二、物理方法：

用200ml量筒取待測溶液，再放入(ru)波美(mei)度計(ji)讀出此時的(de)溶液波美(mei)度（比(bi)(bi)重），根據(ju)氯化鈣(gai)溶液比(bi)(bi)重表查得對(dui)應的(de)百分比(bi)(bi)濃(nong)度。
