Abstract
Ammonium chloride decomposes the technical field that chemical combination experiment demonstrator relates to chemical experiment.Comprise iron stand, U-tube, Y-piece, single hole plug, tool prop up test tube, U-tube is fixed on iron stand by iron clamp, two mouths of pipe of U-tube are all plugged with single hole plug, two conduits are connected with the two ends of Y-piece by emulsion tube through single hole plug, and the other end of Y-piece extend into tool through single hole plug and props up in test tube.The cover on the mouth of pipe that props up that tool props up test tube has balloon.Emulsion tube accompanies tongs.Compared with prior art: by two kinds of drying agent of different nature, eliminate sour gas hydrogen chloride and alkaline gas ammonia respectively, allow residual gas is open-and-shut to be tested out by ph test paper, thus the decomposition of this ammonium salt nitrogenous fertilizer and chemical combination and distillation physically and sublimating is made a distinction, the application is novel in design, rationally, flexible operation is simple and easy, has multiple utility function for structure.
Description
Technical field
The utility model relates to chemical experiment technique field, relates in particular to a kind of ammonium chloride and decomposes chemical combination experiment demonstrator.
Background technology
People teaches the activity in edition senior middle school chemical teaching material required 1 the 4th thematic second section " production of nitrogenous fertilizer and use " part and probes into utilize and heats chloride solid, student is allowed to experience the thermal instability of ammonium salt, its reaction principle is: ammonium chloride is heated and produces hydrogen chloride and ammonia, meets cold chemical combination again and generate chloride solid in the two uphill process.But this experiment is the spitting image of the solid sublimation in physics and phenomenon of sublimating, for pilot process, depend merely on the doubt that theoretical explanation is not enough to answer student's generation, have ignored pilot process.
Utility model content
The utility model institute is for above-mentioned shortcoming and defect, and provide a kind of novel in design, rationally, flexible operation is simple and easy for structure, and the ammonium chloride being convenient to demonstrate pilot process decomposes chemical combination experiment demonstrator.
For solving the problems of the technologies described above, the utility model provides following technical scheme: ammonium chloride decomposes chemical combination experiment demonstrator, comprise iron stand, U-tube, Y-piece, single hole plug, tool prop up test tube, U-tube is fixed on iron stand by iron clamp, two mouths of pipe of U-tube are all plugged with single hole plug, two conduits are connected with the two ends of Y-piece by emulsion tube through single hole plug, and the other end of Y-piece extend into tool through single hole plug and props up in test tube.
As preferably, on the mouth of pipe that tool props up test tube, cover has balloon.
As preferably, emulsion tube accompanies tongs.
Further, bottom U-tube pipe, ammonium chloride is housed, two tube wall parts are plugged with the asbestos being surrounded by NaOH and the asbestos being surrounded by phosphorus pentoxide respectively, and two tube walls of Y-piece are equipped with moistening ph test paper in advance.Above-mentioned U-tube and tool prop up test tube and are all fixed on iron stand.
The beneficial effect that the utility model compared with prior art has is: by two kinds of drying agent of different nature, eliminate sour gas hydrogen chloride and alkaline gas ammonia respectively, allow residual gas is open-and-shut to be tested out by ph test paper, thus the decomposition of this ammonium salt nitrogenous fertilizer and chemical combination and distillation physically and sublimating is made a distinction, the application is novel in design, rationally, flexible operation is simple and easy, has multiple utility function for structure.
Accompanying drawing explanation
Fig. 1 is the utility model one-piece construction schematic diagram.
Number in the figure is: 1-ammonium chloride, and 2-is surrounded by the asbestos of NaOH, 3-single hole plug, the ph test paper that 4-is moistening, 5-balloon, 6-iron clamp, 7-tool props up test tube, 8-Y type pipe, 9-tongs, 10-emulsion tube, 11-conduit, 12-iron stand, 13-is surrounded by the asbestos of phosphorus pentoxide, 14-U type pipe.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As figure assembles instrument, verifying attachment impermeability, loads medicine, closes the tongs 9 of bottom, opens the tongs 9 on top, heating ammonium chloride 1, can see that the ph test paper 4 of hygrometric profit on Y-piece 8 becomes blue, illustrate thus and create ammonia; Close the tongs 9 on top, open the tongs 9 of bottom, heating ammonium chloride 1, can see that the ph test paper 4 of Y-piece 8 times hygrometric profits reddens, illustrate thus and create hydrogen chloride; Open the tongs 9 of upper and lower, heating ammonium chloride 1, can see and produce white cigarette in Y-piece 8 bottom simultaneously, illustrates that ammonia and hcl reaction generate ammonium chloride thus.
Tool with balloon 5 props up test tube 7 can buffer gas flow, and prevents tail gas pollution environment.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
