Abstract
The utility model discloses a kind of new chemical experiment modifying device, comprise U-shaped base, U-shaped pipe, rubber is stifled, funnel, looped pipeline, draw point, soft rubber tube, it is characterized in that: on U-shaped base, have U-lag, U-shaped pipe is placed on U-shaped base, U-shaped pipe passes on left the stifled funnel that is penetrated with of rubber, funnel downward-extension upper glass pipe is in U-shaped pipe, in glass tube, be inlaid with looped pipeline and pass through rubber leak stoppage mouth on funnel, rubber on the U-shaped mouth of pipe on right side blocks end and is connecting soft rubber tube, the inner draw point that is fixedly inserted with of the U-shaped mouth of pipe on right side, draw point lower end is inserted with sodium piece, 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 modifying 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, 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 modifying device, simple to operate, increases the learning interest that improves student, can avoid violent the brought danger of sodium and water reaction in the past, can observe more intuitively the variation of reaction solution.
To achieve these goals, the technical solution of employing is the utility model:
A kind of new chemical experiment modifying device, comprise U-shaped base 1, U-shaped pipe 2, rubber stifled 3, funnel 4, looped pipeline 5, draw point 6, soft rubber tube 7, it is characterized in that: on U-shaped base 1, have U-lag, U-shaped pipe 2 is placed on U-shaped base, U-shaped pipe passes on left rubber stifled 3 and is penetrated with funnel 4, funnel 4 downward-extension upper glass pipes are in U-shaped pipe, in glass tube, be inlaid with looped pipeline 5 and block up 3 leak on funnel 4 by rubber, stifled 3 upper ends of rubber on 2 mouthfuls of the U-shaped pipes on right side are connecting soft rubber tube 7, 2 mouthfuls of inside of U-shaped pipe on right side are fixedly inserted with draw point 6, draw point 6 lower ends are inserted with sodium piece.
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.
The specific embodiment
In conjunction with Fig. 1, present embodiment is described, a kind of new chemical experiment modifying device, comprise U-shaped base 1, U-shaped pipe 2, rubber stifled 3, funnel 4, looped pipeline 5, draw point 6, soft rubber tube 7, it is characterized in that: on U-shaped base 1, have U-lag, U-shaped pipe 2 is placed on U-shaped base, U-shaped pipe passes on left rubber stifled 3 and is penetrated with funnel 4, funnel 4 downward-extension upper glass pipes are in U-shaped pipe, in glass tube, be inlaid with looped pipeline 5 and block up 3 leak on funnel 4 by rubber, stifled 3 upper ends of rubber on 2 mouthfuls of the U-shaped pipes on right side are connecting soft rubber tube 7, 2 mouthfuls of inside of U-shaped pipe on right side are fixedly inserted with draw point 6, draw point 6 lower ends are inserted with sodium piece.
During use, in U-shaped pipe, pack water and phenolphthalein solution into and then cover that rubber is stifled reflects sodium piece and solution on pin, the NaOH that sodium and water reflection generate can make phenolphthalein solution become redness, when sodium and water reaction, in U-shaped pipe, the effect of the liquid level of solution on right side by atmospheric pressure can decline, solution (redness) can spray by being water column sample in the looped pipeline in the glass tube of the funnel on the left of U-shaped pipe, the structure of rubber tube is identical with the structure of base buret head, and the gas that reaction generates just can not emitted when the rolling pearl of not pinching rubber tube head.
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.
