1、计算氢氧化钾和水的比例:这里以30%氢氧化钾溶液为例,那么则需要氢氧化钾30g,水80g。
1. Calculate the ratio of potassium hydroxide to water: take 30% potassium hydroxide solution as an example, then 30g pota...
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...
化学式NaOH,通常被称为烧碱、火碱、苛性钠,是一种强碱,通常是片状或块状形状,具有强腐蚀性。易溶于水(溶于水时放热)并构成碱性溶液,另具潮解性,易于从空气中吸收水蒸气(潮解)和二氧化碳(蜕变),可以参与盐酸检验是否变质。
Chemical formula NaOH, commonly known as caustic soda, cau...
1、保证加氢和氧化剂的 pH。以蒽醌法为原料,在碱环境下进行了操作。加氢溶液的氧化及过氧化剂的提取均需在酸性环境中进行。氢氧化钾氧化溶液在变成碱性后会发生裂解,从而导致事故。
1. Ensure the pH of hydrogenation and oxidant. Anthraquinone method was used in al...
