The reaction demonstration device includes a big test tube with branch, and a rubber plug which is disposed at an opening part of the big test tube with branch, a copper sheet and a drying tube which are disposed in the big test tube with branch, wherein an upper end of the copper sheet and the upper end of the drying copper are respectively provided with a fixation rod, the fixation rods are inserted in the rubber plug, a side wall, which is close to the opening part, of the big test tube with branch is connected with an injector through a rubber pipe, and a stopping clamp is disposed on the rubber pipe. The reaction demonstration device has advantages of being low in price, being simple to assemble, being convenient to operate, being small in pollution, being small in medicine usage amount, being energy-saving, and having three functions. The reaction demonstration device is capable of preparing colorless nitric oxide gas rapidly, facilitating observation of a reaction process of colorless NO gas and O2 in the air, and absorbing NO2 gas generated by the reaction of the colorless NO gas and O2 in the air using NaOH, and is suitable for a demonstration experiment and a student experiment.
Description
Technical field
The utility model relates to the apparatus for demonstrating that reacts of a kind of copper and rare nitric acid.
Background technology
In middle school chemistry experiment teaching, when demonstration copper and dilute nitric acid reaction, general experiment adopts the uncovered vessel such as test tube, beaker, the colourless NO of generation and airborne O
2reaction, the NO of generation rufous
2gas.Mainly there is following shortcoming in this experiment: (1) is due to NO and NO
2for poisonous gas, harm teachers and students are healthy; (2) react uncontrollable, produce a large amount of harmful gases and waste medicine; (3) be difficult to observe colourless NO gas and airborne O
2reaction generates the NO of rufous
2the process of gas, affects teaching efficiency.
Existing closed nitrogen monoxide is produced experiment device for teaching, although the problems referred to above have been carried out to preliminary solution, this device also exists many deficiencies: (1) " U " type pipe is difficult for doing to add thermal reaction apparatus, and heating effect is bad; (2) assembling is complicated, and operation is difficult; (3) drug dosage is many, and experimental cost is high; (4) there is no further to process poisonous NO
2gas.
Utility model content
The purpose of this utility model is to provide a kind of copper and dilute nitric acid reaction apparatus for demonstrating, with solve existing closed nitrogen monoxide produce experiment device for teaching exist assembling complicated, operate difficult problem.
Technical solutions of the utility model are as follows: a kind of copper and dilute nitric acid reaction apparatus for demonstrating, comprise that large tool props up test tube, is located at the rubber stopper that described large tool props up test tube opening part, described large tool props up and in test tube, is provided with copper sheet and drying tube, the upper end of described copper sheet and drying tube is respectively equipped with fixed bar, described fixed bar inserts in described rubber stopper, described large tool props up on the sidewall that test tube approaches opening part and is connected with syringe by proofed sleeve, and described proofed sleeve is provided with tongs.
The utility model device price is low, it is simple, easy to operate to assemble, and pollutes littlely, and drug dosage is few, saves the energy, and phenomenon is obvious, has triple functions.Colourless nitric oxide gas can be produced fast, colourless NO gas and airborne O can be observed again
2course of reaction, can also absorb and process O in colourless NO gas and air with NaOH
2the NO that reaction generates
2gas, is suitable for lecture experiment and student experimenting.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral implication is as follows: large tool props up test tube (1), rare nitric acid (2), copper sheet (3), drying tube (4), rubber stopper (5), fixed bar (6), tongs (7), proofed sleeve (8), syringe (9).
Embodiment
As shown in the figure, a kind of copper and dilute nitric acid reaction apparatus for demonstrating, comprise that large tool props up test tube 1, is located at the rubber stopper 5 that large tool props up test tube 1 opening part, large tool props up and in test tube 1, is provided with copper sheet 3 and drying tube 4, the upper end of copper sheet 3 and drying tube 4 is respectively equipped with fixed bar 6, fixed bar 6 inserts in rubber stoppers 5, and large tool props up on the sidewall that test tube 1 approaches opening part and is connected with syringe 9 by proofed sleeve 8, and proofed sleeve 8 is provided with tongs 7.
The utility model is specifically implemented as follows:
1. assembling process: copper sheet 3 is tied up on fixed bar 6; Fixed bar can adopt thin wire.In drying tube 4, fill calcium carbonate, with fixed bar 6 tightens; Packing copper sheet 3 and drying tube 4 into large tool props up in test tube 1; Fixed bar, respectively through rubber plug 5, is propped up rubber plug 5 plugs on test tube 1 at large tool.
2. reinforced process: add a certain amount of rare nitric acid in large tool props up test tube 1.In drying tube 4, fill calcium carbonate.
3. course of reaction: heat large tool and prop up test tube 1, open tongs 7, drying tube 4 is slowly declined and enters large tool and prop up in the rare nitric acid in test tube 1, when syringe 9 moves to right by the time, close tongs 7, copper sheet 3 declines are entered to large tool and prop up in the rare nitric acid in test tube 1, copper sheet and rare nitric acid generation chemical reaction generate colourless N0 gas.
4. processing procedure: open tongs 7, with syringe 9, the large tool of air Injection is propped up in test tube 1, see that NO props up the O in test tube with large tool at once
2contact reaction generates the NO of rufous
2gas.Then inject NaOH, color has disappeared again at leisure.
Claims (1)
1. a copper and dilute nitric acid reaction apparatus for demonstrating, comprise that large tool props up test tube (1), be located at the rubber stopper (5) that described large tool props up test tube (1) opening part, it is characterized in that: described large tool props up and in test tube (1), is provided with copper sheet (3) and drying tube (4), the upper end of described copper sheet (3) and drying tube (4) is respectively equipped with fixed bar (6), described fixed bar (6) inserts in described rubber stopper (5), described large tool props up on the sidewall that test tube (1) approaches opening part and is connected with syringe (9) by proofed sleeve (8), described proofed sleeve (8) is provided with tongs (7).
