Abstract
The utility model discloses an experimental device for measuring oxygen content of air. The experimental device comprises two wide-mouth bottles, wherein one wide-mouth bottle is filled with white phosphorus, scale lines are marked on the outer part of the wide-mouth bottle, a bottle plug is arranged at the bottle mouth, a short glass delivery tube is inserted into the bottle plug, one end of the short glass delivery tube is communicated with the wide-mouth bottle, and the other end of the short glass delivery tube is communicated with a rubber delivery tube; and the other end of the rubber delivery tube is connected with a long glass delivery tube, a clip is arranged on the rubber delivery tube, and the long glass delivery tube is inserted into the other wide-mouth bottle which is filled with red ink. The experimental device has the advantages that the device is not required to be opened for heating in demonstrative experiment, the device is good in sealing property, pollution is avoided, and errors of experimental results are small and the like.
Description
Technical field
The utility model relates to a kind of teaching and experimental demonstration instrument, relates in particular to a kind of experimental provision of measuring oxygen content in the air.
Background technology
Because school does not have to measure on the textbook device of oxygen content in the air, and the device of in the past measuring with red phosphorus need heat with spirit lamp.Will cause atmospheric pollution like this, increase the error probability of measurement result simultaneously.
Summary of the invention
The purpose of the utility model provides a kind of convenient experimental provision of measuring oxygen content in the air.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of experimental provision of measuring oxygen content in the air; Comprise: two wide-necked bottles is characterized in that: in one of them wide-necked bottle white phosphorus is housed, wide-necked bottle has scale mark outward; Bottle mouth position is equipped with bottle stopper; Be inserted with short grass tube on the bottle stopper, one of short grass tube feeds in the wide-necked bottle, and the other end is communicated with rubber catheter; The other end of rubber catheter connects a long grass tube, and rubber catheter is provided with clip, and long grass tube inserts in another wide-necked bottle, in this wide-necked bottle red ink is housed.
The utility model lecture experiment has does not need device for opening heating, good airproof performance, and can not produce pollution, advantage such as the experimental result error is little.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing: 1, rubber catheter; 2, long grass tube; 3, wide-necked bottle; 4, red ink; 5, scale mark; 6, wide-necked bottle; 7, lack grass tube; 8, bottle stopper; 9, white phosphorus; 10, clip.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:
The experimental provision of oxygen content is as shown in Figure 1 in the utility model mensuration air; Comprise: two wide-necked bottles 3 and wide-necked bottle 6, be equipped with white phosphorus 9 in one of them wide-necked bottle 6, the wide-necked bottle 6 outer scale marks 5 that have; Bottle mouth position is equipped with bottle stopper 8; Be inserted with short grass tube 7 on the bottle stopper 8, one of short grass tube 7 feeds in the wide-necked bottle 6, and the other end is communicated with rubber catheter 1; The other end of rubber catheter 1 connects a long grass tube 2, and rubber catheter 1 is provided with clip 10, and long grass tube 2 inserts in another wide-necked bottle 3, in this wide-necked bottle 3 red ink 4 is housed.
Experimental procedure:
The wide-necked bottle 6 that 1, will fill white phosphorus 9 is placed in the hot water and heats, and takes out when having waited a large amount of white cigarettes to produce, and is placed on the desktop and cools off.
2,4 li of the red ink that wide-necked bottle 6 complete cool to room temperature such as, an end of long grass tube 2 are placed in another wide-necked bottle 3 are opened clip 10, observe the volume that red ink gets into wide-necked bottle 6.
Advantage: because school does not have to measure on the textbook device of oxygen content in the air, and the device of in the past measuring with red phosphorus need heat with spirit lamp.Will cause atmospheric pollution like this, increase the error probability of measurement result simultaneously.This experiment has does not need device for opening heating, good airproof performance, and can not produce pollution, advantage such as the experimental result error is little.
