Abstract
A kind of burner of white phosphorus, comprise the beaker that hot water is housed, be placed on the white phosphorus in beaker, stretch in hot water the wireway leading to white phosphorus, it is characterized in that: described wireway is the glass bend pipe of square, the lower end of described wireway is connected with the bell mouth of putting upside down, described bell mouth is positioned at directly over beaker white phosphorus, described lural periphery is provided with supplying hot water breach inwardly or outwardly, the upper end of described wireway is connected with hydraucone and is plugged with plug, described plug can be connected with syringe with puncturing, described syringe inner chamber is communicated with wireway by the hollow needle of front end.By oxygen intake in syringe, be connected after the needle pierces plug of front end with wireway, promote piston, the white phosphorus place of Xiang Shuizhong passes into oxygen, can find that ventilation is then fired, stuffiness is then put out, then flame of ventilating is ventilated greatly, less, and then flame is little, combustion efficiency can arbitrarily control, effective also very interesting.
Description
Technical field
The utility model relates to a kind of experimental apparatus of high school chemistry teaching, particularly a kind of burner of white phosphorus.
Background technology
Junior middle school chemistry teaching will study the condition of burning, wherein the submerged combustion experiment of white phosphorus is used for verifying that oxygen is one of condition of burning, experimental program is: placed in the hot water by white phosphorus, hot water temperature exceedes white phosphorus kindling point, but white phosphorus can not burn, limit oxygen producing limit wireway passes into oxygen in hot water again, can find that white phosphorus takes fire, and illustrates that oxygen is the necessary condition of burning.This experimental program Problems existing is: one is that oxygen producing limit, limit wireway passes into oxygen in hot water, and the inconvenience of air-flow size controls, and experiment effect is not good.Two is troublesome poerations, utilizes wireway to the white phosphorus oxygen blast gas in water, and the white phosphorus in water can be taken advantage of a situation everywhere " disorderly dynamic ", and experiment is not easy to control very much, and operation easier is larger.
Utility model content
For overcoming the problems referred to above, the utility model proposes a kind of burner of white phosphorus, require to reach experiment effect good, be easy to manipulate, object easy to use.
The technical scheme that the utility model adopts is: a kind of burner of white phosphorus, comprise the beaker that hot water is housed, be placed on the white phosphorus in beaker, stretch in hot water the wireway leading to white phosphorus, it is characterized in that: described wireway is the glass bend pipe of square, the lower end of described wireway is connected with the bell mouth of putting upside down, described bell mouth is positioned at directly over beaker white phosphorus, described lural periphery is provided with supplying hot water breach inwardly or outwardly, the upper end of described wireway is connected with hydraucone and is plugged with plug, described plug can be connected with syringe with puncturing, described syringe inner chamber is communicated with wireway by the hollow needle of front end.
The beneficial effects of the utility model are: by oxygen intake in syringe, be connected after the needle pierces plug of front end with wireway, promote piston, the white phosphorus place of Xiang Shuizhong passes into oxygen, can find that ventilation is then fired, stuffiness is then put out, then flame of ventilating is ventilated greatly, less, and then flame is little, combustion efficiency can arbitrarily control, and experiment effect is well also very interesting, is beneficial to the learning interest of the student given full play to.White phosphorus is limited in the bell mouth of putting upside down, can not everywhere " disorderly dynamic ", convenient experimental operation.Syringe is connected with wireway by syringe needle, plug, taking-up syringe needle, to facilitate in oxygen collecting device oxygen intake again, is beneficial to many experiments and many classes of experiments.The white cigarette that white phosphorus burning generates is only absorbed by the water, and also can avoid contaminated air.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1 syringe, 2 syringe needles, 3 plugs, 4 hydraucones, 5 wireways, 6 beakers, 7 hot water, 8 breach, 9 bell mouths, 10 white phosphorus.
Embodiment
As shown in Figure 1, beaker 6 is built with hot water 7, white phosphorus 10 is placed with in beaker, the bell mouth 9 of putting upside down is covered with above white phosphorus 10, the periphery of bell mouth 9 is provided with supplying hot water breach 8 inwardly or outwardly, bell mouth 9 is connected to the lower end of wireway 5, wireway 5 is for being bent into rectangular-shaped glass bend pipe, the upper end of wireway 5 is connected with hydraucone 4 and is plugged with plug 3, plug 3 be thicker than the length being less than syringe needle 2 on syringe 1, after syringe needle 2 pierces through plug 3, the inner chamber of syringe 1 is communicated with wireway 5.
White cigarette (the P that white phosphorus burning generates
2o
5) can be only absorbed by the water, thus avoid contaminated air, if with 0.The sodium hydroxide solution of 1% replaces water, then be more conducive to absorbing the phosphorus pentoxide generated.
