片状氢氧化钾制成粉末状的氢氧化钾步骤

发布来源:http://www.jinhao360.com    更新时间:2022-05-07 点击数:

氢氧化钾与氢氧化钠在普通实验室条件下是必然要潮解的,粉碎的状态下潮解更快,不可能准确称量。所以如果只是为了在普通条件下准确称量而想要粉碎片状氢氧化钾的话,就不用考虑了。

Potassium hydroxide and sodium hydroxide are bound to deliquesce under ordinary laboratory conditions. Deliquescence is faster in the state of crushing, so it is impossible to weigh accurately. Therefore, if you want to crush flake potassium hydroxide just for accurate weighing under ordinary conditions, you don't have to consider it.
方法 #1 在干燥气氛下操作,最简单的就是在惰性气体保护下的手套箱或者手套袋里称量;
The method #1 is to operate in a dry atmosphere. The simplest way is to weigh in a glove box or glove bag under the protection of inert gas;
#2 考虑到氢氧化钾一般在溶液中使用,那么可以称取大致的量,溶解于相应的溶剂中,然后用滴定的方法确定真实浓度,滴定的具体流程需要根据溶剂的种类确定,相关信息网上有大量可以获取,另外,注意密封容器以保护溶液不被空气中的二氧化碳所破坏;

#2 considering that potassium hydroxide is generally used in solution, the approximate amount can be weighed and dissolved in the corresponding solvent, and then the real concentration can be determined by titration. The specific process of titration needs to be determined according to the type of solvent, and a large amount of relevant information can be obtained on the Internet. In addition, pay attention to sealing the container to protect the solution from being damaged by carbon dioxide in the air;
Plan B:如果你足够大条地觉得10%以内的误差可以接受(俺大条地赶脚其实一般都可以啦),那就弄个spatula捣捣碎(注意不要吸入氢氧化钾粉末哦,很呛人的)再快速称量吧。
Plan B: if you think the error of less than 10% is acceptable (I can generally catch up with my feet), make a spatula and mash it (be careful not to inhale potassium hydroxide powder, which is very choking) and then weigh it quickly.
