Technical field
The utility model relates to a kind of laboratory chemical experimental instrument, specifically the property experiment instrument of sodium.
Background technology
Sodium is typical metallic element, and at middle school period, the chemical property of research sodium mainly comprises two aspects: the one, and sodium burns in air, and the 2nd, the reaction of sodium and water.The method that the most teaching materials of the experiment that sodium burns in air adopt is to heat on asbestos gauge, and this method not only experiment success rate is low, is difficult to obtain the flaxen sodium peroxide of products of combustion, and can damages asbestos gauge, causes unnecessary waste.It is that sodium burns in crucible that the people teaches edition regular senior secondary school's required method that 1. adopts of curricular standard experiment textbook, test in this way, and the student is not easy to observe experimental phenomena, and the demonstration effect is relatively poor.The reaction of sodium and water, owing to be not easy to collect the gas that generates when reacting, the check of gaseous product becomes the difficult point of experiment, has all removed this experimental implementation in the three cover new curriculum senior middle school chemical teaching materials.In addition, taking the method that sodium metal usually adopts is to cut from different directions with pocket knife, and the experimental implementation complexity has certain danger, and the biscuit metal sodium that cuts down often is bonded on the pocket knife, and it is very inconvenient to use.
Summary of the invention
The purpose of this utility model provides a kind of taking conveniently, and simple to operate, security is good, the property experiment instrument of the sodium that success ratio is high.
For achieving the above object, technical solution of the present utility model is as follows:
The property experiment instrument of the utility model sodium comprises: sodium metal dispenser, sodium metal burner, container, gas collector, sodium and water reactor.
The property experiment instrument of aforesaid sodium, wherein said sodium metal dispenser is made up of straight tube and piston, straight tube inner wall smooth, outer wall is provided with the annulus of two projectioies near the bottom, straight tube front end has certain tapering, can reduce the resistance when drilling through sodium metal, piston can closely insert in the straight tube and can promote up and down.
The property experiment instrument of aforesaid sodium, wherein said sodium metal burner is to be processed into glass tube, and wherein an end is thicker, is used to hold sodium metal and makes it burning to sodium metal heating, and the other end is thinner.
The property experiment instrument of aforesaid sodium, wherein said container one side is provided with oblique groove, can put the sodium metal dispenser in the groove, fills in the container to drip the water that phenolphthalein solution is arranged, and is used to test the reaction of sodium and water.
The property experiment instrument of aforesaid sodium, wherein said gas collector one end is provided with conduit, is connected with sharp nozzle tube with hose on the conduit, and the other end is provided with bottleneck, can collect the gas of sodium and water reaction generation with drainage.
The property experiment instrument of aforesaid sodium, wherein said sodium and water reactor wall are provided with small sircle hole, and vessel port has certain tapering, can be connected the lower end of sodium metal dispenser securely.
The utlity model has and take conveniently, simple to operate, security is good, and the advantage that success ratio is high utilizes this cover instrument can carry out the property experiment of middle school period sodium.

Embodiment
Below in conjunction with description of drawings and specific embodiment the technical solution of the utility model is described in detail.
1, takes sodium metal and observe sodium deepening in air
With the part between hand-tight 6 two annulus 8 of straight tube and 9 that hold on sodium metal dispenser 1, and note not making the palm of the hand withstand the upper end of piston 7, as using boring cutter, pierce at leisure in the sodium metal, make straight tube lower end be filled with one section sodium metal, can observe the silvery white metallic luster of sodium by straight tube 6.Pass piston 7 gently, the sodium piece is exposed a little, cut crust, can observe the very fast deepening of argenteous metallic luster of sodium.
2, sodium burns in air
After reaction stopped, the mouth of pipe continued to keep red heat a period of time.Just can observe the product of reaction after a while---the granular solid matter of flaxen millet.
3, the collection of the reaction of sodium and water and gaseous product and check
Couple together with the conduit 11 and the sharp nozzle canula 16 of hose 15 with gas collector 4, put container 3 into, add suitable quantity of water, make in the gas collector 4 to be full of water, water only presss from both sides 17 and clamps hose 15 again.
The vessel port 14 of sodium and water reactor 5 is fixed on the lower end of sodium metal dispenser 1, and the sodium piece is gone out when preventing to react.Then said apparatus is put in the groove 10 of container 4, insert in the water, be placed on the lower end of gas collector 4 bottlenecks 12, push the piston 7 of sodium metal dispenser 1 gently, extrude remaining sodium metal, sodium and water generate gas at sodium and water reactor 5 internal reactions, and near liquid reddens, and the gas of generation directly is collected in 4 li of gas collectors by drainage.
If gas is less, gas collector 4 to be mentioned, bottleneck facing to spirit lamp flame, can be heard sharp-pointed explosion downwards.If be full of gas in the gas collector 4, can fetch boiling water and only press from both sides 17, the water in the container 3 enters in the gas collector 4 very soon, and gas is discharged from, and light at 16 mouthfuls of places at sharp nozzle canula, can hear the sound of slight " puff ".
The above, be not that the utility model is done any pro forma restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations, in every case do not break away from the technical solutions of the utility model content,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
