Abstract
The utility model relates to a sodium peroxide and carbon dioxide reaction experiment demonstration apparatus, which not only is simple in apparatus, convenient in operation and obvious in phenomenon, but also can enable the energy change in the experiment process to be visualized, and comprises a U-shaped tube, wherein the middle and upper portion of the right side of the U-shaped tube is provided with a block of cotton, and sodium peroxide is arranged on the cotton and covered with a block of absorbent cotton. The sodium peroxide and carbon dioxide reaction experiment demonstration apparatus has the advantages of: 1 being simple in apparatus, convenient in operation and obvious in phenomenon, and being very safe and environmental protection; 2 enabling the energy change in the experiment process to be visualized thereby being convenient for students to observe; and 3 being helpful for culturing learning interest and divergent thinking of the students and building scientific and active learning atmosphere.
Description
Technical field
The utility model relates to that a kind of not only apparatus is simple, easy to operate, and phenomenon is obvious, and the sodium peroxide and the carbon dioxide reaction experimental demonstration device of energy changing that can the reaction experiment process, belongs to chemical devices and makes the field.
Background technology
Sodium peroxide and carbon dioxide reaction can generate oxygen; This is the critical nature of sodium peroxide; Utilize this experiment can sodium peroxide to be used in breathing apparatus or the submarine source as oxygen, practicality very, however do not relate to this lecture experiment on the teaching material; Can not confirm through experimental phenomena, be unfavorable for student's Interest Cultivation like this.
The utility model content
Purpose of design: avoid the weak point in the above-mentioned background technology, it is simple, easy to operate to design a kind of not only apparatus, and phenomenon is obvious, and the sodium peroxide and the carbon dioxide reaction experimental demonstration device of energy changing that can the reaction experiment process.
Design proposal: in order to realize above-mentioned purpose of design.The middle and upper part on U-shaped pipe the right is equipped with a cotton, and sodium peroxide powder is placed on the cotton, is stamped the design of an absorbent cotton on the sodium peroxide powder, is the major technique characteristic of the utility model.The purpose of doing like this is: soda mint can generate carbon dioxide with the dilute sulfuric acid reaction, and sodium peroxide and carbon dioxide reaction generate oxygen, can produce heat energy in the course of reaction; Oxygen has combustibility, can make the absorbent cotton burning, and this is the experimental principle of this experiment; The cotton that place on U-shaped pipe right side can prevent that powder from falling, and U-shaped pipe bottom adds sodium bicarbonate powder, and dilute sulfuric acid adds from U-shaped pipe left port; Block left port with stopper rapidly after the adding, prevent that the carbon dioxide that produces from overflowing from left port, react with sodium peroxide fully; The heat that reaction produces and the oxygen of generation make rapid zoom of absorbent cotton and burning, when needs demonstration sodium peroxide and carbon dioxide reaction experiment, adopt the application's apparatus simple; Easy to operate, phenomenon is obvious, safety very, environmental protection; And the energy changing that can reflect experimentation intuitively helps to cultivate students'interest in learning and divergent thinking and construction science, positive study atmosphere.
Technical scheme: a kind of sodium peroxide and carbon dioxide reaction experimental demonstration device, U-shaped pipe vertical tube on one side is built-in with two layers of cotton core, is between first chemical reagent is deposited between two-layer cotton core, and U-shaped pipe bottom is between second chemical reagent deposits in.
The utility model is compared with background technology, and the one, apparatus is simple, and is easy to operate, and phenomenon is obvious, safety very, environmental protection; The 2nd, can reflect the energy changing of experimentation intuitively, be convenient to observation of students; The 3rd, help to cultivate students'interest in learning and divergent thinking and construction science, positive study atmosphere.
Description of drawings
Fig. 1 is the structural representation of sodium peroxide and carbon dioxide reaction experimental demonstration device.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of sodium peroxide and carbon dioxide reaction experimental demonstration device, U-shaped pipe 1 vertical tube on one side is built-in with two layers of cotton core 2 and 4, and two- layer cotton core 2 and 4 are between first chemical reagent is deposited 3, are between second chemical reagent deposits in 5 bottom the U-shaped pipe.The cotton core 4 that is positioned at U vertical tube 1 upper strata is absorbent cotton.
The first mistake chemical reagent is that sodium oxide molybdena powder 3, the second chemical reagent are sodium bicarbonate powder 5, and dilute sulfuric acid 6 adds from U-shaped pipe 1 left port, and its manufacture craft is a prior art, is not described herein at this.
What need understand is: though the foregoing description is to the mentality of designing of the utility model detailed text description of contrasting; But these text descriptions; Just the simple text of the utility model mentality of designing is described; Rather than to the restriction of the utility model mentality of designing, any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the utility model.
Claims (2)
