Abstract
The utility model relates to an experimental device for combustion of sodium in chlorine gas, wherein, the experimental device is simple to operate, less steps are needed, chlorine gas can be prepared, and experimental phenomena can be reflected at the same time. The experimental device comprises a separating funnel and a big flask, wherein, the separating funnel is arranged on a double hole plug fitting into a bottle mouth of the big flask; a drying tube A is arranged on the other hole of the double hole plug; and a rubber plug for a pipe orifice is connected with a branch pipe of a drying tube B. The experimental device has the advantages as follows: firstly, less facilities for an experiment are needed, the steps are simple, and the experimental device is convenient to operate; secondly, the preparation of chlorine gas and the verification of combustion of sodium metal in chlorine gas can be carried out in the same device, the experiment is simpler, and the success rate is increased greatly; and thirdly, the steps are reduced, so that chlorine gas can be prevented from escaping outwards, and the experimental device is very safe and environment-friendly.
Description
Technical field
The utility model relates to a kind of not only simple to operate, and step is few, and can prepare sodium combustion experiment device in chlorine that chlorine reflects experimental phenomena simultaneously, belongs to chemical devices and makes the field.
Background technology
On the chemistry class, when doing the experiment of in chlorine, burning, need in advance chlorine to be prepared about sodium; Cause leaking of chlorine easily like this, contaminated environment has certain potential safety hazard simultaneously, in the experimentation; Need to put into combustion spoon to sodium, with the alcolhol burner heating, step is more loaded down with trivial details; Bring many troubles for teacher student, and experiment can not guarantee very success rate.
The utility model content
Purpose of design: avoid the weak point in the above-mentioned background technology, design a kind of not only simple to operately, step is few, and can prepare sodium combustion experiment device in chlorine that chlorine reflects experimental phenomena simultaneously.
Design: in order to realize above-mentioned purpose of design.Separatory funnel is placed on the diplopore that matches with big flask 2 bottlenecks beyond the Great Wall, and the A drying tube places on another hole of diplopore plug, the rubber stopper of the mouth of pipe and B drying tube the design that links to each other of arm, be the major technique characteristic of the utility model.The purpose of doing like this is: concentrated hydrochloric acid and potassium permanganate reaction generate chlorine, and sodium can burn in chlorine and generate sodium chloride, and this is the experimental principle of this experiment, is added into concentrated hydrochloric acid in the separatory funnel; Big drag is equipped with potassium permanganate, opens the control valve on the separatory funnel, concentrated hydrochloric acid is splashed in the potassium permanganate react, and produces great amount of heat in the time of the chlorine of generation; Chlorine contacts with sodium metal through the arm of A drying tube, and the sodium metal surface slowly becomes white, and then fierce burning in chlorine produces a large amount of cigarette shape solid sodium chloride in the drying tube A; Fill with sufficient soda lime in the B drying tube, guarantee fully chlorine to be absorbed the device of not overflowing; When needs experimentize, adopt the application can prepare the purpose that chlorine reflects experimental phenomena simultaneously, simple in structure; Step is few, and is easy to operate, and experimental phenomena is obvious; Device has good air-tightness, has guaranteed that chlorine does not leak in the experimentation, and safety very, environmental protection have guaranteed experiment success very simultaneously.
Technical scheme: a kind of sodium is the combustion experiment device in chlorine; It comprises separatory funnel, big flask; Said separatory funnel is placed on the diplopore that matches with big flask bottleneck beyond the Great Wall, and the A drying tube places on another hole of diplopore plug, the rubber stopper of the mouth of pipe and B drying tube arm link to each other.
The utility model is compared with background technology, and the one, it is few to test used device equipment, and step is simple, and is easy to operate; The 2nd, preparation chlorine and checking sodium metal burn in chlorine and can on same device, carry out, and make experiment simpler, and success rate increases greatly; The 3rd, the minimizing of step can avoid chlorine not leak, safety very, environmental protection.
Description of drawings
Fig. 1 is the structural representation of sodium combustion experiment device in chlorine.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of sodium is the combustion experiment device in chlorine, and it comprises separatory funnel 1, big flask 2, and said separatory funnel 1 is placed on the diplopore plug 3 that matches with big flask 2 bottlenecks; A drying tube 4 places on another hole of diplopore plug 3, the rubber stopper of the mouth of pipe and B drying tube 5 arm link to each other, 4 mouths of pipe of A drying tube are placed with one deck cotton core; Sodium metal 6 places on the cotton core; Fill with soda lime 7 in the B drying tube 5, add concentrated hydrochloric acid 8 in the separatory funnel 1, big flask 2 bottoms are equipped with potassium permanganate 9; 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.
