Abstract
The utility model discloses an experiment device for the chemical reaction between sodium and water. The experiment device comprises a U-shaped pipe (1); distilled water (2) containing phenolphthalein is arranged in the U-shaped pipe (1); a first rubber plug (5) is arranged at the right end of the U-shaped pipe (1); an air outlet pipe (6) and a steel needle (4) both communicated with the distilled water (2) are plugged on the first rubber plug (5); a sodium block (3) is arranged on the steel needle (4) at the end plugged into the distilled water (2); a second rubber plug (7) is arranged at the left end of the U-shaped pipe (1); and a funnel (8) is plugged into the second rubber plug (7). By adopting the structure, the property of sodium can be conveniently and safely examined.
Description
Technical field
The utility model relates to a kind of chemical experiment device, relates in particular to the reaction of a kind of sodium and water chemistry and uses experimental provision.
Background technology
In chemical teaching material, the experiment of sodium and water reaction is carried out in double dish or beaker, in this experiment, can observe solution and become redness, has generated gas in the judgment experiment of moving about through the sodium bead.But can't check the gas of generation through the experimental provision on the textbook.In teaching, just student question is arranged: the gas that produces in this reaction is hydrogen, how not pass through experimental check? Teach in edition legacy version the people; This experiment is to make reactor with small beaker; Collect the gas that produces with small test tube, redden after check has explosion, reacted solution to drip the phenolphthalein test solution.Though this experiment all has checking to two kinds of products; But this experimental implementation difficulty is big slightly; And the NaOH that the reaction back generates is highly basic, though Generation Liquid concentration is very little, how much has corrosivity; We collect small test tube that gas arranged from just being reluctant hand put in to take out this liquid at heart like this, thus should experiment operation like this neither be quite reasonable.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, safety, and experimental provision is used in the sodium of the character of convenient check sodium and water chemistry reaction.
The technical scheme of the utility model is that experimental provision is used in a kind of sodium and water chemistry reaction; It comprises; U-shaped pipe 1 is characterized in that: in said U-shaped pipe 1, be provided with and drip the distilled water 2 that phenolphthalein is arranged, the right-hand member of said U-shaped pipe 1 is provided with first rubber plug 5; Be inserted with the escape pipe 6 and draw point 4 that communicate with said distilled water 2 on said first rubber plug 5; Be provided with sodium piece 3 on the said draw point 4 and at an end that inserts distilled water 2, the left end of said U-shaped pipe 1 is provided with second rubber plug 7, is inserted with funnel 8 on said second rubber plug 7.
The technical scheme of the utility model is coated with aluminium foil 9 in addition on said sodium piece 3, said aluminium foil 9 has a plurality of apertures.
The beneficial effect of the utility model is to drip the distilled water 2 that phenolphthalein is arranged through in said U-shaped pipe 1, being provided with, and the right-hand member of said U-shaped pipe 1 is provided with first rubber plug 5, is inserted with the escape pipe 6 and draw point 4 that communicate with said distilled water 2 on said first rubber plug 5; Be provided with sodium piece 3 on the said draw point 4 and at an end that inserts distilled water 2, the left end of said U-shaped pipe 1 is provided with second rubber plug 7, is inserted with funnel 8 on said second rubber plug 7; During experiment, it is violent that sodium piece 8 touches the water afterreaction, can see that the liquid level on U-shaped pipe 1 the right descends along with the carrying out of reaction; Explanation has produced gas as U-shaped pipe 1 the right of reactor; This gas is water insoluble, and the right air pressure of instrument is increased, and gas presses down liquid level; Because whole device is a linker; According to law of connected vessels, the liquid level on U-shaped pipe 1 left side will rise, thereby has entered into funnel 8 to prevent overflowing of U-shaped pipe 1 left side liquid.There is the water of phenolphthalein test solution to become redness owing to drip in the U-shaped pipe 1, explains in the reaction to have generated alkaline matter, i.e. NaOH; Gas is lighted quietly burning of back, and flame is blue, explains that the gas that generates is hydrogen; Realized safety like this, the purpose of the character of convenient check sodium.

Embodiment
According to shown in Figure 1, the utility model relates to a kind of sodium and experimental provision is used in the water chemistry reaction, and it comprises; U-shaped pipe 1 is provided with in said U-shaped pipe 1 and drips the distilled water 2 that phenolphthalein is arranged, and the right-hand member of said U-shaped pipe 1 is provided with first rubber plug 5; Be inserted with the escape pipe 6 and draw point 4 that communicate with said distilled water 2 on said first rubber plug 5; Be provided with sodium piece 3 on the said draw point 4 and at an end that inserts distilled water 2, on said sodium piece 3, be coated with aluminium foil 9, said aluminium foil 9 has a plurality of apertures; The left end of said U-shaped pipe 1 is provided with second rubber plug 7, is inserted with funnel 8 on said second rubber plug 7; During experiment, it is violent that sodium piece 8 touches the water afterreaction, and see and produced gas; Near liquid has become redness, and the liquid level on U-shaped pipe 1 the right descends along with the carrying out of reaction, explains that U-shaped pipe 1 the right as reactor has produced gas; This gas is water insoluble, and the right air pressure of instrument is increased, and gas presses down liquid level; Because whole device is a linker, according to law of connected vessels, U-shaped pipe 1 the right liquid level descends; The liquid level on U-shaped pipe 1 left side will rise, thereby has entered into funnel 8 to prevent overflowing of U-shaped pipe 1 left side liquid.There is the water of phenolphthalein test solution to become redness owing to drip in the U-shaped pipe 1, explains in the reaction to have generated alkaline matter, i.e. NaOH; Gas is lighted quietly burning of back, and flame is blue, explains that the gas that generates is hydrogen; Realized safety like this, the purpose of the character of convenient check sodium.
