This standard solution was accurately prepared in super-clean laboratory with potassium chloropatinate-crystallized cobaltous chloride and sub-packed in 20 ml ampoules.
本标准溶液以氯铂酸钾和氯化钴在超净实验室中准确配制并分装于20 毫升安瓿中。
The influencing factor was studied quantitatively. The result showed that the amount of water was suitably controlled under 6% when making up the potassium hydroxide-enthanol standard solution.
对影响因素进行了定量研究，结果表明，配制氢氧化钾-乙醇标准溶液时，加水量宜控制在6%以下。
