将钠切成很薄的小片,利用小刀与钠的附着力稀疏的放入硬质玻璃管中。制氯则用研成粉末的高锰酸钾预盛入烧瓶中,用浓盐酸预盛入开关漏斗中。装置如图,都不加热,只须把分液漏斗打开,即有浓厚的氯气射入玻管中,薄钠片与氯的接触面积大,反应速度快其所生之热足以使纳本身达成熔融,故能反应剧烈发出黄光,仅数秒钟就成了洁白的食盐而试管安全无恙。应注意:起初射入之氯要浓,若稀了则反应慢,表面生成之食盐造成隔离状态,以后便无法进
The sodium cut into thin pieces, the use of a knife and sodium adhesion sparse into the hard glass tube. Chlorine is made with powdered potassium permanganate pre-Sheng into the flask, pre-filled with concentrated hydrochloric acid into the funnel. Device shown in Figure, are not heated, just open the separatory funnel, that is, a thick chlorine into the glass tube, the contact area of thin sodium tablets and chlorine large, fast response to the heat generated by its satisfied Melting, it can send a yellow light fierce reaction, only a few seconds to become white salt and test tube safe and sound. It should be noted: the initial injection of chlorine to be thick, if the reaction is slow, the salt generated on the surface of the isolation state, will not be able to enter
