人民教育出版社出版的2001年6月第1版义务教育课程标准实验教科书《化学》九年级上册第33～34页上,关于用过氧化氢制取氧气的实验是分3步进行的:1.将带火星的木条伸入盛有5 mL 5%的过氧化氢溶液的试管中,木条不能复燃。2.将带火星的木条伸入经微热后的盛有过氧化氢溶液的试管中,显示木条复燃。3.将带火星的木条伸入盛有5 mL 5%的过氧化氢溶液且有少量的二氧化锰的试管中,显示木条复燃。但我们经过反复的实验证明,第2步实验基本上不能实现
People’s Education Press, June 2001 1st edition compulsory education curriculum standard experimental textbook “Chemistry” ninth grade on the first volume page 33 ~ 34, on hydrogen peroxide hydrogen production experiment is carried out in three steps: 1 Insert the strips of Mars into a test tube containing 5 mL of 5% hydrogen peroxide solution and the sticks can not be re-ignited. 2. Insert the strips of Mars into the test tube containing the hydrogen peroxide solution after the micro-heat, showing the wood burning again. 3. Insert the Martian strip into a tube containing 5 mL of 5% hydrogen peroxide in a small amount of manganese dioxide and show the wood burning. However, after repeated experiments, we proved that the second experiment is basically impossible
