高中化学(乙种本)上册实验1—4氯水分解实验装置有三个明显的不足:一、药品用量大,二、由于圆底烧瓶瓶口较大,使得瓶内的氯水与水槽中的水相互扩散,反应生成的部分氧气会逸出瓶外;其三,产生的氧气不便检验。为
There are three obvious deficiencies in the experimental 1-4 chlorine water decomposing experimental device of the High School Chemistry (Type B) booklet: First, the amount of the drug is large, and secondly, the larger the bottle mouth of the round bottom flask, the chlorine water in the bottle and the water in the water tank. The water spreads to each other, and part of the oxygen produced by the reaction escapes out of the bottle. Third, the oxygen produced is inconvenient to test. for
