Abstract
A verification demonstrator for reaction between sodium and water and a product thereof relates to a chemical instrument. The technical scheme adopted for resolving technical problems includes that the demonstrator is formed by a cylindrical container, a large opening, a balloon sleeved on the large opening, a small opening and a sharp-mouth pipe inserted on the small opening, a rubber head which can be detached at any time is arranged on the sharp-mouth pipe, the cylindrical container made of transparent hard plastic materials or glass, and the sharp-mouth pipe is a glass tube or a syringe needle. Compared with an existing reaction container, the verification demonstrator has simple operation, is easy for collection of generated gas, can demonstrate experiment image of reaction between sodium and water, can verify reaction products and the like.
Description
Technical field
The utility model relates to a kind of instruments used for education, particularly the instrument of sodium and water reaction experiment demonstration.
Background technology
In high school chemistry teaching, sodium and water reaction are modal reactions, reaction is carried out in beaker usually, and in order to verify its reaction product, often needing to collect the gas that produces with test tube verifies, this experiment method not only bothers for the collection of gas, and the product adversary has corrosive attack in collection, does not have special reaction vessel.
The utility model content
The utility model mainly is at problem, and the instrumentation of a kind of sodium and water reaction is provided, simultaneously the demonstration device that can also verify reaction product.
The technical scheme that above-mentioned technical matters to be solved in the utility model adopted is: sodium and water reaction and product checking demonstration device thereof, form by hydrostatic column and balloon etc., and two openings of big opening and little opening are arranged above the hydrostatic column; Be with balloon above the big opening, be plugged with sharp nozzle tube on the little opening; The glue head that can take off is at any time arranged above the sharp nozzle tube; Hydrostatic column is transparent duroplasts material or glass, and sharp nozzle tube is glass tube or syringe needle.
Compare with existing reaction vessel, the utlity model has easy and simple to handlely, collect easily the gas that produces, can demonstrate the experiment imagination of sodium and water reaction, simultaneously advantage such as energy confirmatory reaction product.
Description of drawings
Fig. 1 is the utility model structure front elevation
Among the figure: 1, hydrostatic column, 2, big opening, 3, little opening, 4, balloon, 5, sharp nozzle tube, 6, water, 7, the sodium piece, 8, the glue head.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Reaction of sodium and water and product checking demonstration device thereof as shown in Figure 1 are made up of hydrostatic column 1, big opening 2 and the balloon 4 that is with above thereof, little opening 3 and the sharp nozzle tube 5 of pegging graft above thereof.
During use, with cover gluings above the sharp nozzle tube 58, in hydrostatic column 1, inject water 6 near fast full state, sodium piece 7 put into balloon 4 and drive the air of balloon 4 away, balloon 4 is enclosed within on the big opening 2 then, with the hand extruding sodium piece 7 in the balloon 4 is put into hydrostatic column 1, sodium and water reaction experiment begin to carry out.After reaction finishes, take off glue head 8, push gassiness balloon 4, light sharp nozzle tube 5 simultaneously, small beaker on cover above the burned flame can be verified the gas of generation; Take off balloon 4, in big opening 2, add phenolphthalein reagent, can verify another product.
Claims (3)
1. reaction of sodium and water and product checking demonstration device thereof are made up of hydrostatic column (1) and balloon (4) etc., it is characterized in that: (3) two openings of big opening (2) and little opening are arranged above the hydrostatic column (1).
