Abstract
The utility model discloses a copper and concentrated nitric acid reaction experiment demonstration device, which comprises a first plastic transparent shell injector (1), a second plastic transparent shell injector (2), a connection hose (3), a fixed iron clamp (4) and a fixed frame (5) and is characterized in that: the first plastic transparent shell injector (1) is vertically fixed on the fixed iron clamp (4); and the first plastic transparent shell injector (1) is connected with the second plastic transparent shell injector (2) through the connection hose (3). The utility model has the advantages that: the copper and concentrated nitric acid reaction experiment demonstration device can control the reaction rate, has a simple structure and is convenient to operate; poisonous gas, such as nitrogen dioxide, cannot overflow; materials are readily available; and the experiment cost is saved.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of safe copper and red fuming nitric acid (RFNA) reaction experiment apparatus for demonstrating.
Background technology
At present, there is following shortcoming in existing device in the teaching material: on the one hand, the experimental implementation of copper and red fuming nitric acid (RFNA) reaction is in the teaching material, adds copper sheet in vitro, in test tube, adds the 1-2ml red fuming nitric acid (RFNA) again.Reaction is carried out immediately, and reaction is violent, is difficult to control, and experimentation can discharge toxic gas nitrogen dioxide, is detrimental to health.On the other hand, the processing of nitrogen dioxide is reasonable inadequately, clogs the test tube mouth with the cotton balls that dips in sodium hydroxide solution in the teaching material, and this method can only absorb a certain amount of nitrogen dioxide, also can cause overflowing of nitrogen dioxide.
Summary of the invention
The utility model provides a kind of copper and red fuming nitric acid (RFNA) reaction experiment apparatus for demonstrating to the deficiency of prior art.This copper and red fuming nitric acid (RFNA) reaction experiment apparatus for demonstrating can be controlled reaction rate, can not cause overflowing of toxic gas nitrogen dioxide, and simple in structure, easy to operate, material is easy to get, and practice thrift experimental cost.
The technical scheme of the utility model is: copper and red fuming nitric acid (RFNA) reaction experiment apparatus for demonstrating; Comprise: the first plastic, transparent shell syringe 1, the second plastic, transparent shell syringe 2, connect flexible pipe 3, fixedly iron clamp 4, fixed mount 5; It is characterized in that: the first plastic, transparent shell syringe 1 vertically is fixed on fixedly on the iron clamp 4, connects with connecting flexible pipe 3 between the first plastic, transparent shell syringe 1 and the second plastic, transparent shell syringe 2.
The said first plastic, transparent shell syringe 1, the second plastic, transparent shell syringe 2 all adopt corrosion-resistant transparent polypropylene or polythene material.
The said first plastic, transparent shell syringe 1, the second plastic, transparent shell syringe, 2 capacity are 20ml; Soft 3 length of said connecting pipe are 20cm.
The utility model has the advantages of and be: 1. this patent carries out method of operating to copper and being employed in of red fuming nitric acid (RFNA) reaction in the obturator; Can control reaction rate; Can let reaction stop at any time, can not cause overflowing of toxic gas nitrogen dioxide, more safety and environmental protection.2. do experiment material with student's life material or discarded object at one's side, meet new curriculum reform spirit, more can excite student's experiment to probe into desire, also embody a kind of economy consciousness.3. simple to operate, material is easy to get, and practices thrift experimental cost.
Description of drawings
Fig. 1 is the utility model concrete structure synoptic diagram
Accompanying drawing indicates: 1 is that the first plastic, transparent shell syringe, 2 is that the second plastic, transparent shell syringe, 3 is that fixedly iron clamp, 5 is fixed mount for connecting flexible pipe, 4
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in Figure 1; Copper and red fuming nitric acid (RFNA) reaction experiment apparatus for demonstrating; Comprise: the first plastic, transparent shell syringe 1, the second plastic, transparent shell syringe 2, connect flexible pipe 3, fixedly iron clamp 4, fixed mount 5; It is characterized in that: the first plastic, transparent shell syringe 1 vertically is fixed on fixedly on the iron clamp 4, connects with connecting flexible pipe 3 between the first plastic, transparent shell syringe 1 and the second plastic, transparent shell syringe 2.
The said first plastic, transparent shell syringe 1, the second plastic, transparent shell syringe 2 all adopt corrosion-resistant transparent polypropylene or polythene material.
The said first plastic, transparent shell syringe 1, the second plastic, transparent shell syringe, 2 capacity are 20ml; Soft 3 length of said connecting pipe are 20cm.
Should be appreciated that the above detailed description of the technical scheme of the utility model being carried out by preferred embodiment is schematic and nonrestrictive.Those of ordinary skill in the art can make amendment to the technical scheme that each instance is put down in writing on the basis of reading the utility model instructions, perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the spirit and the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
