Description
one, technical field
the utility model belongs to chemical field, relates to a kind of chemical experiment device, particularly for demonstrating the experiment that on junior middle school chemistry textbook, carbon dioxide and water react.
two, background technology
the ninth grade chemistry textbook first volume the 42nd page of carbon dioxide that Shanghai education publishing house publishes in January, 2012 and the experiment that water reacts, it is demonstration like this in textbook: the bottle cap opening a bottle of pop, with the rubber stopper jam-pack pop bottle of band wireway, wireway is stretched in the test tube that purple reindeer moss test solution is housed, vibrate pop bottle gently, the carbon dioxide be dissolved in carbonated drink escapes, and generate with water effect material---the carbonic acid that purple reindeer moss test solution is taken on a red color, then to the heating liquid taken on a red color, solution becomes purple again.Textbook does experiment existing defects like this: carbon dioxide passes in purple reindeer moss test solution, purple reindeer moss test solution reddens look, and this is that carbon dioxide makes the variable color of purple reindeer moss test solution on earth, or the carbonic acid generated after reaction makes it redden look, can not affirm, lack persuasion.
