氢氧化钾是一种常见的无机碱,常温下为白色粉末或片状固体。其性质与氢氧化钠相似。它具有强碱性和腐蚀性。那么氢氧化钾的相对分子量和用途是什么?
Potassium hydroxide is a common inorganic base, which is white powder or flake solid at room tempera...
简单来说,能区分两个物质酸碱性强弱的叫做区分溶剂,否则就叫做拉平溶剂。题目中说的氢氧化钠和氢氧化钾同时溶解在水中,都会完全电离,这就是说二者被水这个溶剂拉平了,而表现出了相同的碱性。如果采用乙醇或液氨等作为溶剂,即可区分出二者碱性的强弱。
In short, the solvent that can distinguish the aci...
在SDS - PAGE中,配胶时需加入TEMED和过硫酸铵,它的作用是什么?但将凝胶液加入在制胶器后需在其上慢慢加入一层乙醇或异丙醇或水

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 labor...
氢氧化钾,是一种常见的无机碱,常温下为白色粉末或片状固体。性质与氢氧化钠相似,具强碱性及腐蚀性,极易吸收空气中水分而潮解,吸收二氧化碳而成碳酸钾,微溶于醚。当溶解于水、醇或用酸处理时产生大量热量。
Potassium hydroxide, a common inorganic base, is a white powder or flak...
氢氧化钾再生产的过程实际上是比较复杂的,而且再生产之后的质量也是有差距的,这是怎么回事呢?下面就来详细讲讲吧。
