Embodiment Construction

[0009] The present invention will be further described in detail with reference to the accompanying drawings and examples.

[0010] like figure 1 , the present invention simulates the lightning method to synthesize nitric oxide demonstration instrument, including test tube 1, central electrode 2, comb-shaped electrode 3, plug 4, button 5 and high-voltage module 6, the comb-shaped electrode 3 has sharp protrusions one by one . The material used for the central electrode 2 and the comb-shaped electrode 3 is metal copper.

[0011] The high-voltage module 6 can provide high-voltage power to the whole device, the button 5 can close or disconnect the entire circuit, the central electrode 2 is in the center of the test tube 1, the comb-shaped electrode 3 is close to the test tube wall, the test tube mouth is closed with a plug 4, and the plug 4 Use insulating material.

[0012] When in use, press the button 5 and the high-voltage module 6 supplies power to the central electrode 2 ...

Abstract

The invention discloses a demonstrating instrument for nitrogen monoxide synthesis by a thunder and lightning simulating method. The demonstrating instrument comprises a test tube, a central electrode, a comb electrode, a stopper, a key and a high-voltage module, wherein the comb electrode is provided with a plurality of sharp protrusions. The central electrode and the comb electrode are made of metal copper. When the demonstrating instrument is used, the key is pressed down to enable the high-voltage module to supply power to the central electrode and the comb electrode, high voltage is formed between the central electrode and the comb electrode, and discharge is performed between the protrusions of the comb electrode and the central electrode, so that a thunder and lightning simulating effect is achieved and nitrogen monoxide is generated. Since the nitrogen monoxide is extremely reactive in chemical property, the nitrogen monoxide and oxygen in the test tube react to generate reddish brown nitrogen dioxide. Therefore, nitrogen monoxide synthesis by thunder and lightning simulation according to color change is achieved.

Description

technical field [0001] The invention relates to a teaching instrument, in particular to a chemical instrument. Background technique [0002] It is mentioned in the high school chemistry textbook that lightning can cause oxygen and nitrogen to react to generate nitric oxide, which cannot be simulated intuitively in the actual teaching process, which makes students deeply impressed. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to let students see the experimental phenomenon and form a deep impression through intuitive simulation. [0004] In order to solve the above technical problems, the present invention simulates the lightning method to synthesize nitric oxide demonstration instrument, including test tube, central electrode, comb-shaped electrode, plug, button and high-voltage module, the comb-shaped electrode has sharp protrusions one by one. The material used for the central electrode and the comb-shaped electrode is...
