一、原料:铝、纯碱、石灰粉。 二、反应原理:用纯碱与石灰反应制取烧碱,烧碱与铝反应制得氢气。 三、制取氢气实验:实验所用的铝片是回收药瓶盖或废铝线,因为纯碱价格便宜,所以用过量的石灰粉与纯碱反应制取烧碱,再用过量的烧碱和铝片反应 First, raw materials: aluminum, soda ash, lime powder. Second, the reaction principle: Soda ash and lime reaction system, caustic soda and aluminum reaction of hydrogen. Third, the system of hydrogen production experiment: the aluminum plate used in the experiment is the recovery of medicine bottle cap or scrap aluminum line, because soda ash cheap, so with an excessive amount of lime powder and soda ash reaction to obtain caustic soda, and then excessive caustic soda and aluminum reaction
