甘汞制备

1.将氯化汞溶解到热水中，然后通入二氧化硫，即可得到白色的Hg2Cl2沉淀。产物经过滤、洗涤、干燥后避光保存。此外，用汞和氯化汞在一起研磨也可制得氯化亚汞。

2.将氯化汞在用盐酸酸化的热水中溶解，然后向该溶液滴加氯化亚锡溶液，使产生白色的Hg2Cl2沉淀。产品经过滤、洗涤、干燥后避光保存。在制备Hg2Cl2的过程中，氯化亚锡不可过量。否则氯化亚汞会被进一步还原为金属汞，使沉淀变黑。

3.分别将氯化钠和硝酸亚汞溶于水中，并用硝酸酸化硝酸亚汞溶液，在搅拌下，将硝酸亚汞水溶液加到氯化钠溶液中，进行反应：

将反应物避光静置，沉淀完全后分离出上层清液，加入冷水搅拌混匀，静置澄清，分出上层清液，用水洗涤沉淀至合格（样品中加入硝酸银稍稍变浑），过滤，干燥得分析纯氯化亚汞。
