NH3和HCl气体都极易溶于水。为此,笔者设计了可对NH3的化学性质中的与水反应和与氯化氢反应得到直观体现的实验,可谓一举两得。一、实验材料圆底具支烧瓶、铁架台、导管、止水夹、饮料瓶等。二、实验特点改进该实验具有以下特点:1.能培养和提高学生进行实验探究的综合性思维和操作技能,拓宽学生的化学知识视野。2.对学生高考化学综合实验的解题具有一定辅助作用。3.实验器材除烧瓶
NH3 and HCl gases are very soluble in water. To this end, I designed the chemical properties of NH3 can react with water and hydrogen chloride reaction was intuitive to reflect the experiment can be described as double benefit. First, the experimental material round bottom with a flask, iron stand Taiwan, catheters, stop clips, beverage bottles. Second, the experimental features to improve the experiment has the following characteristics: 1. To cultivate and improve students to explore the integrated thinking and operational skills, broaden students' field of chemical knowledge. 2. The students of college entrance examination chemical comprehensive solution to the problem has some auxiliary role. 3. Experimental equipment in addition to flask
