Description
Technical field
The utility model belongs to chemistry teaching test equipment field, and in particular to a kind of properties of carbon dioxide experimental demonstration
Device.
Background technique
The property of carbon dioxide is the very important content of junior middle school chemistry, and five experiments of teaching material design are to probe into titanium dioxide
The property of carbon: the fire fighting test of carbon dioxide；Carbon dioxide is reacted with water；It is molten that purple reindeer moss is added dropwise in arbon dioxide solution
Liquid, reheating；It is blown with glass tube into clear limewash.This design is not perfect, does not solve following problems: 1. containing
Have and water is added in the plastic bottle of carbon dioxide, plastic bottle is deflated, is that carbon dioxide is dissolved in water or carbon dioxide and water has occurred
Reaction；2. make that reindeer moss solution reddens color is carbon dioxide or carbonic acid；3. redden reindeer moss solution heating after again purpling, be
Carbon dioxide evolution or carbonic acid decompose；4. it is blown with mouth into limewash, it is both unhygienic, it is also dangerous.5. all experimentss
It takes a long time.
Summary of the invention
Topple over the purpose of the utility model is to provide a kind of carbon dioxide and property experiment device, to efficiently solve existing
There is the problem of technology.
To realize that the purpose of this utility model adopts the technical scheme that: a kind of properties of carbon dioxide experiment demonstrator, packet
Include gas bottle and beaker, it is characterised in that: three holes of three hole rubber stopper of gas bottle bottle plug, three hole rubber stoppers are filled in slightly respectively
Glass tube, a branch pipe of U-tube a, U-tube b a branch pipe, another branch pipe of U-tube a and U-tube b fills in small glue
Beaker is arranged in plug, gas bottle side, and bracket is equipped in beaker, and bracket upper section and lower section are distinguished fixed combustion spoon, set on combustion spoon
Set candle.
Dry purple litmus paper on the raw glass pipe nozzle transparent sticker.
Purple reindeer moss solution is housed in the U-tube a, clarification limewash is housed in U-tube b.
The beneficial effects of the utility model are:
1. simplifying experimental provision, reduce experimental procedure.5 properties of carbon dioxide can be verified simultaneously with the device.
1. cannot burn.2. cannot be combustion-supporting.3. density ratio air is big.Carbonic acid is generated 4. can react with water.5. clear lime can be made
Water becomes cloudy.
2. more than is reacted while being carried out, and experimental period is shortened.
3. perfect experimental design.It is additionally arranged the experiment that carbon dioxide cannot make dry litmus paper change colour, it was demonstrated that two
Carbonoxide is reacted with water generates carbonic acid, and carbonic acid makes purple reindeer moss solution redden color.In addition, out of U-tube limewash become cloudy and
Reindeer moss solution reddens two experimental phenomenas of color, can also illustrate that the density ratio air of carbon dioxide is big.
4. carbon dioxide is toppled over by raw glass pipe, carbon dioxide is effectively prevent to bleed around, improve experiment at
Power.
5. containing candle with combustion spoon, it is convenient to place, convenient for operation.
Detailed description of the invention
Fig. 1 is utility model diagram；
In figure: 1- gas bottle, 2- raw glass pipe, tri- hole rubber stopper of 3- U-tube a, 4- U-tube b, 5-, the small rubber plug of 6-,
7- beaker, 8- bracket, 9- combustion spoon, 10- candle, 11- purple litmus paper.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
Equipment: gas bottle (500mL) 1, raw glass pipe (diameter 10mm) 1, three hole rubber stoppers 1, U-tube 2,
1, beaker (200 mL), small rubber plug 2, combustion spoon 2,2, candle (1cm long), purple litmus paper.
Reagent: clarification limewash purple reindeer moss solution
Application method:
1. being inserted into a raw glass pipe, 2 U-tubes respectively on three hole rubber stoppers.
2. the dry purple litmus paper on raw glass nozzle transparent sticker, is inverted three hole rubber stoppers, in U-tube
1-2mL purple reindeer moss solution is injected in a, injection 1-2mL clarifies limewash in U-tube b, distinguishes small rubber plug beyond the Great Wall.
3. collecting full carbon dioxide in gas bottle, sheet glass is covered.
4. gas bottle is turned around, three hole rubber stopper beyond the Great Wall rapidly.
5. observing phenomenon: limewash gradually becomes cloudy；Purple reindeer moss solution gradually reddens color；Dry purple litmus paper
It is non-discolouring.
6. removing the purple litmus paper of raw glass nozzle.
7. the carbon dioxide in gas bottle is poured into the beaker for being placed with ladder candle by raw glass pipe along walls of beaker, it can
Observe: candle flame successively extinguishes from the bottom to top.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
