一、原料：铝、纯碱、五灰粉。二、反应原理：用纯碱与石灰反应制烧碱，烧碱与铝反应制氢气。三、制取氢气：铝片是回收药瓶盖或废铝线，因为纯碱价格便宜，所以用过量的五灰粉与纯碱反应制取烧碱，再用过量的烧碱和铝片反应制取氢气。四、制取氢气球1制取氢气的设备：充气机是 First, raw materials: aluminum, soda ash, five gray powder. Second, the reaction principle: soda ash and lime reaction system, caustic soda and aluminum reaction hydrogen. Third, the system of hydrogen: Aluminum is the recovery of medicine bottle cap or scrap aluminum line, because soda ash cheap, so with an excess of ash and soda ash reaction of sodium hydroxide, and then excess caustic soda and aluminum reaction hydrogen. Fourth, the preparation of hydrogen balloon system 1 Preparation of hydrogen equipment: inflator is
