Description
Technical field
The utility model relates to the chemical experimental instrument field, is specially integrated chlorine character demonstrating experiment device.
Background technology
Chemistry is the science of composition, structure, character and Changing Pattern of research material, is human in order to understanding with transform one of intramundane main method and means.In the chemo that secondary and high school is offered; Various chemical experiments play a very important role to the teaching tool of chemistry, through chemical experiment, can make the student better grasp rudimentary knowledge and basic skills; Improve the ability of the knowledge of applying in a flexible way; We can say that experiment is exactly the soul of chemistry, is the glamour and the main source that excites student's learning interest of chemistry, cultivates and develop the important method and the means of students ' thinking ability and innovation ability especially.
All there is a lot of deficiencies in demonstration reaction experiment for chlorine character in regular senior secondary school's curricular standard experimental teaching material and Catholicism material at present.
At first be to do when producing chlorine, can when experiment finishes, retain a large amount of chlorine tail gas, wireway is extend in the beaker that fills sodium hydroxide solution though adopt in order to prevent the pollution that these tail gas cause human body; Let chlorine and sodium hydroxide solution react, to absorb these unnecessary gas, still owing to chlorine flowrate in the laboratory is big; When toxic gas gets in the sodium hydroxide solution; Because surface of contact is less, fully reaction in time, the gas that causes not reacted is prone to from solution, emerge; Contaminated air, and serious suck-back phenomenon more also may take place in amount of chlorine.
Next is when doing the experiment that sodium reacts in chlorine; Exist the consumption of chlorine in the experiment big on the one hand; Cause the problem of the waste of medicine; In the experimental implementation process, there is chlorine excessive on the other hand inevitably, during for example as if asbestos gauge that uses in the experiment and gas collection bottleneck poor sealing, also can influences the effect of experiment greatly.Simultaneously, the experiment in these two kinds of teaching materials all need be heated or light, and in air, lights the Na that generates on the sodium surface in advance such as sodium
2O
2Influence sodium and in chlorine, burn, and sodium not that burning the time can make chlorine outwards overflow in closed device, so can make the classroom environment pollution more serious yet.
Doing the different experiments chamber exactly once more, needing different experiment equipments, troublesome poeration not only, and increased the probability that chlorine is revealed, very be unfavorable for the healthy of student, especially do the healthy of the teacher that will thresh experiment.
Summary of the invention
