Abstract
The utility model discloses a kind of new chemical experiment easy reaction device, comprise iron stand, straight glass tube, glass fine duct, wireway, plug is stifled, wide-necked bottle, bracing frame, it is characterized in that: on iron stand, be fixedly connected with two bracing frames, on the bracing frame of the left and right sides, be provided with respectively straight glass tube clip and funnel retainer plate, straight glass tube blocks by plug up and down, plug stifled pegging graft wireway and the pin of upside, on wireway, connecting inflatable ball, under pin, there is sodium piece, the plug of straight glass tube lower end blocks up and is connected with one end of glass fine duct, the glass fine duct other end is connected with wide-necked bottle and puts in 1-2 centimetre in wide-necked bottle, on wide-necked bottle, be carved with scale and at bottom opening, product design of the present utility model is reasonable, simple in structure, easy to use.
Description
Technical field
The utility model relates to chemical experiment technique with the apparatus field, is specifically related to a kind of new chemical experiment sodium and water reaction easy device.
Background technology
Chemical experiment proof when doing sodium and water reaction experiment and observe has gas and alkali lye to generate, normally in beaker, put into water and phenolphthalein solution, then with tweezers gripping sodium piece, be placed in solution, with test tube, collect reacted gas, Deng the long-pending full gas of test tube, then with hand, block test tube mouth, there is drawback in such operation, it is highly basic that sodium and water reaction generates NaOH, there is very strong corrosivity, although NaOH can have certain corrosion imperceptible to skin, but be that impact is healthy eventually, when being collected, reflection gas bothers very much simultaneously, have plenty of reaction mouthful place be placed with beaded glass sebific duct (beaded glass sebific duct is identical with base buret header structure) thereby and then near flame being moved to beaded glass sebific duct release reaction gas obtain experimental result, secondly, chemical experiment is dry as dust, student does not often have too large interest to doing experiment, how chemical experiment is accomplished safe and efficient strong operability and can increase the interest of learning to become development need from now on.
Utility model content
The purpose of this utility model is to provide a kind of new chemical experiment sodium and water reaction easy device, simple to operate, the collection of convenient experiment reacting gas, when having increased test interesting, improve student's learning interest, violent the brought danger of sodium and water reaction in the past can be avoided, the variation of reaction solution can be observed more intuitively.
To achieve these goals, the technical solution of employing is the utility model:
A kind of new chemical experiment easy reaction device, comprise iron stand 1, straight glass tube 2, glass fine duct 3, wireway 4, plug stifled 5, wide-necked bottle 6, bracing frame 7, it is characterized in that: on iron stand 1, be fixedly connected with two bracing frames 7, on the bracing frame 7 of the left and right sides, be provided with respectively straight glass tube clip and funnel retainer plate, straight glass tube 2 blocks up 5 by plug up and down and seals, the plug of upside stifled 5 pegging graft wireway 4 and pin, on wireway 4, connecting inflatable ball, under pin, there is sodium piece, the plug stifled 5 of straight glass tube 2 lower ends is connected with one end of glass fine duct 3, glass fine duct 3 other ends are connected with wide-necked bottle 6 and put in the interior 1-2 centimetre of wide-necked bottle 6, on wide-necked bottle 6, be carved with scale and at bottom opening.
The beneficial effect that the utility model can produce: reasonable in design, simple in structure, easy to use, simple to operate and not dangerous can observation intuitively reacted the variation of solution afterwards, increased the interest of Students ' Learning.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
In conjunction with Fig. 1, present embodiment is described, a kind of new chemical experiment easy reaction device, comprise iron stand 1, straight glass tube 2, glass fine duct 3, wireway 4, plug stifled 5, wide-necked bottle 6, bracing frame 7, it is characterized in that: on iron stand 1, be fixedly connected with two bracing frames 7, on the bracing frame 7 of the left and right sides, be provided with respectively straight glass tube clip and funnel retainer plate, straight glass tube 2 blocks up 5 by plug up and down and seals, the plug of upside stifled 5 pegging graft wireway 4 and pin, on wireway 4, connecting inflatable ball, under pin, there is sodium piece, the plug stifled 5 of straight glass tube 2 lower ends is connected with one end of glass fine duct 3, glass fine duct 3 other ends are connected with wide-necked bottle 6 and put in the interior 1-2 centimetre of wide-necked bottle 6, on wide-necked bottle 6, be carved with scale and at bottom opening.
During use, in straight glass tube, pack water and phenolphthalein solution into and then cover that plug is stifled reflects sodium piece and solution on pin, the NaOH that sodium and water reflection generate can make phenolphthalein solution become redness, liquid level of solution when sodium and water reaction in straight glass tube can decline by the effect of atmospheric pressure, solution (redness) can spray by glass fine duct and form the interest that little fountain shape is convenient to student's observation increase Students ' Learning from funnel, the plug of straight glass tube upper end blocks and is connecting rubber tube, the structure of rubber tube is identical with the structure of base buret head, the gas that reaction generates can enter into inflatable ball by wireway, when reacting, take off inflatable ball the finish time.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
