Preferably, a soft rubber plug and a cotton ball are respectively arranged on two openings of the duplex test tube, and the soft rubber plug is positioned right above the alcohol lamp.
Preferably, the soft rubber plug is inserted with a needle head of a syringe with the specification of 1mL, the syringe is filled with 0.25mL of 5% sodium hydroxide solution,
preferably, a red litmus test paper placed in the duplex test tube is arranged below the soft rubber plug, and an ammonium sulfate crystal placed on the inner wall of the bottom of the duplex test tube is arranged below the red litmus test paper.
The utility model discloses in, a verify ammonium nitrogen fertilizer and alkali pyrogen formation ammonia's miniaturation environment-friendly device altogether, have that the medicine quantity is few, pollute less, save time, easy operation, experimental phenomenon advantage such as obvious, effectively prevent the loss of ammonia, prevent air pollution. The experiment can be demonstrated by teachers, and students can perform experiments in groups, so that the experiment is simple and practical.
Drawings
FIG. 1 is a schematic structural view of a micro-environment protection apparatus for verifying ammonia gas generation by co-heating ammonium nitrogen fertilizer and alkali.
In the figure: 1 iron stand, 2 duplex test tubes, 3 alcohol lamps, 4 syringes, 5 soft rubber plugs, 6 red litmus test paper, 7 cotton balls and 8 ammonium sulfate crystals.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1, a verify ammonium nitrogen fertilizer and alkali and generate trace environment-friendly device of ammonia altogether, iron stand platform 1 includes base and support, and fixed mounting has the iron clamp on one side of support, has placed pair test tube 2 on the iron clamp, and alcohol burner 3 has been placed to the roof of base, and alcohol burner 3 is located the below of pair test tube 2.
The utility model discloses in, install soft plug 5 and cotton ball 7 on two openings of duplex test tube 2 respectively, soft plug 5 is located alcohol burner 3 directly over, and cotton ball 7 passes through the water is moist.
In the utility model, the soft rubber plug 5 is inserted with the needle of the injector 4 with the specification of 1mL, and the injector 4 is internally provided with 0.25mL of 5 percent sodium hydroxide solution with concentration.
The utility model discloses in, 5 below of flexible glue stopper are equipped with the red litmus test paper 6 of placing in duplex test tube 2, and red litmus test paper 6 passes through the water and wets, and the below of red litmus test paper 6 is equipped with places ammonium sulfate crystal 8 on the inner wall of duplex test tube 2 bottoms, and the quality of ammonium sulfate crystal 8 is about 0.2 g.
The utility model discloses in, the experimentation: connect the instrument earlier, the gas tightness of inspection device puts alcohol burner 3 on band iron clip pallet 1, and the test tube bottom on the pair test tube 2 left side is packed into 0.2g ammonium sulfate crystal 8, fixes pair test tube 2 above alcohol burner 3 on band iron clip pallet 1. Two pieces of red litmus test paper 6 which are wet by water are stuck to the middle upper part of the left test tube of the duplex test tube 2 side by side, a cotton ball 7 which is wet by water is placed at the right test tube opening of the duplex test tube 2, 0.25mL of 5% sodium hydroxide solution is absorbed by a 1 mL-specification injector 4, the injector 4 penetrates through a soft rubber plug 5 to plug the left test tube of the duplex test tube 2 tightly, the injector 4 is pushed slightly, so that the 5% sodium hydroxide solution in the injector 4 is dripped into the left test tube of the duplex test tube 2, an alcohol lamp 3 is ignited, the test tube is preheated firstly and then heated. It is observed that bubbles are generated at the bottom of the test tube on the left side of the duplex test tube 2, the wet red litmus test paper 6 on the wall of the test tube turns blue, the alcohol lamp 3 is removed, the ammonium sulfate crystal and the sodium hydroxide solution are mixed and heated together to release ammonia gas, and the excessive ammonia gas escaping from the test tube at the other end is absorbed by water in the wet cotton ball 7 at the opening of the test tube, so that the environment is prevented from being polluted.
