Abstract
A hypochlorous acid decomposition demonstration device relates to the technical field of chemical teaching aids and is composed of a spherical drying tube, an organic glass tube and an ultraviolet lamp tube. Two ends of the organic glass tube are plugged by rubber plugs, the thin end of the spherical drying tube penetrates through the rubber plug at the upper portion to extend into the organic glass tube, the ultraviolet lamp tube penetrates through the two rubber plugs at the upper portion and the lower portion, and two ends of the ultraviolet lamp tube are connected with a wire and a control system. A T-shaped tube penetrates through the rubber plug at the lower portion to extend into the organic glass tube, the other two ends of the T-shaped tube are respectively connected with latex tubes, water stopping clamps are clamped on the latex tubes, and one latex tube is connected with an ordinary funnel for adding liquid. Cotton is filled in the thick end of the spherical drying tube, and a cover with a hole is covered at the thick end. Compared with the prior art, the hypochlorous acid decomposition demonstration device uses simple articles which are easy to obtain, can obviously demonstrate decomposition of hypochlorous acid and verify products, can be used continuously, and is free of pollution, simple in structure and worth popularizing.
Description
Technical field
The utility model relates to the technical field of chemical lecture experiment, is that hypochlorous acid decomposes demonstration device specifically.
Background technology
Typical traditional experiment of senior chemistry when chlorine water is seen the experiment of photolysis, what adopt on the teaching material is in flask, to place chlorine water and the method for being exposed to the sun is in the sun carried out, the method receives temperature; The particularly influence of sunlight strength, DeGrain, and can't verify the character of the gas of generation; Be unfavorable for that the student grasps its real character; How to carry out the displaying that hypochlorous acid decomposes, make phenomenon more obvious, also do not have special teaching aid at present.
The utility model content
The purpose of the utility model is the deficiency to prior art, and the chemical teaching aid of the obvious observe phenomena of a kind of ability with the checking product is provided, and promptly hypochlorous acid decomposes demonstration device.
The purpose of the utility model realizes through following technological means: hypochlorous acid decomposes demonstration device; Form by spherical drying tube, plexi-glass tubular, T type pipe and quartz burner; Said plexi-glass tubular two ends are stopped up with plug; The thin end of spherical drying tube passes the top plug and stretches in the plexi-glass tubular, and quartz burner passes two plugs in upper and lower, and the quartz burner two ends link to each other with control system with lead.
Said T type pipe passes the bottom plug and stretches in the plexi-glass tubular, and the other two ends of T type pipe link to each other with emulsion tube respectively, accompany tongs above the emulsion tube, and one of them emulsion tube is connected with the common funnel that is used for liquid feeding.
Be plugged with cotton in the butt end of said spherical drying tube, be stamped lid with holes above.
Compared with prior art the utlity model has following tangible advantage: utilize be simple and easy to article; Can significantly show hypochlorous decomposition and checking product, can use continuously, pollution-free; Simple in structure, be a kind of chemical demonstration teaching aid that promotional value is arranged very much.
Description of drawings
Fig. 1 is the utility model synoptic diagram.
1. cottons wherein, lid 2. with holes, 3. spherical drying tube, 4. funnel, 5. plug, 6. emulsion tube, 7. plexi-glass tubular, 8. tongs, 9.T type pipe, 10. lead, 11. quartz burners.
Embodiment
Below in conjunction with description of drawings the utility model is done further to describe in detail:
The use that this hypochlorous acid decomposes demonstration device is: connect device by figure, the jam-pack plug is opened the tongs 8 on the emulsion tube 6 that is connected with common funnel 4, steps up another tongs 8; In plexi-glass tubular 7, inject chlorine water through common funnel 4, when chlorine water is full of in the whole plexi-glass tubular 7, step up tongs 8, energising; Can observe the decomposition of chlorine water, energising a period of time is when producing a large amount of bubbles; Stop energising; Can be placed on the gas that the check of spherical drying tube 3 places produces with the batten of ashes, can observe the resume combustion phenomenon, thereby verify the product that hypochlorous acid decomposes.
In a word, the utility model provides hypochlorous acid to decompose demonstration device.The above; Be merely a part of embodiment of the utility model; The protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
