On, with single hole rubber stopper (6) stoppered test tube (3) mouth with gas-guide tube (7).Equipped with ammonium hydrogen carbonate solid (2) and white sulfuric acid
The interior reeded test tube (3) of copper solid (5) is fixed on the iron stand with iron clamp (4), and test tube (3) mouth slightly tilts down.With
First emulsion tube (8) connects the gas-guide tube (7) of single hole rubber stopper (6) outer end and the side pipe of T shape pipe (13).By wet red stone
Stamen test paper (9) is put into small funnel (10), with the second emulsion tube (12) connection with spring clip (11) equipped with wet red stone
Small funnel (10) the lower end nozzle of stamen test paper (9) and the upper end tube nozzle of T shape pipe (13).The dress clarification limewash in beaker (14),
In beaker (14) of the lower end nozzle of T shape pipe (13) insertion equipped with clarification limewash, when experiment, open spring clip (11), first
Give test tube (3) bottom heating with alcolhol burner (1) flame envelope, after alcolhol burner (1) flame envelope be fixed on be placed with ammonium hydrogen carbonate solid (2)
Position heating.It can be seen at this time ammonium hydrogen carbonate solid is constantly reduced, white copper sulphate solid gradually becomes blue, it is red to moisten
Phenomena such as color litmus paper (9) becomes blue, clear limewash becomes cloudy, fastening spring presss from both sides after observing the above phenomenon
(11), it allows the gas of generation to be all passed through in clarification limewash, prevents ammonia leakage from polluting air in air.Occur above existing
As the reason of be chemical reaction has occurred after ammonium hydrogen carbonate is heated to generate water, ammonia and carbon dioxide gas, the water of generation to flow to
It reacts in the groove of test tube mouth with white copper sulphate solid contact and generates the copper sulfate crystal of blue；Due to ammonia
Density ratio air is small, thus the ammonia generated from the upper end tube nozzle of T shape pipe (13) come out with it is wet red in small funnel (10)
Color litmus paper (9) contact, makes wet litmus red test paper become blue, and the density ratio air of carbon dioxide gas is big, institute
It is come out with carbon dioxide gas from the lower end nozzle of T shape pipe (13) and is contacted with clarification limewash, become cloudy clarification limewash, three
Kind product respectively obtains inspection.The above phenomenon sufficiently proves that ammonium hydrogen carbonate solid is chemically reacted when heated, generates ammonia
Gas and water and carbon dioxide gas.
The utility model has the following beneficial effects: device is simple, easy to operate, phenomenon is obvious；Bicarbonate can be verified respectively
Three kinds of products that ammonium is thermally decomposed, convincingness are strong；It is safe and environment-friendly pollution-free.It is versatile, it had both been applicable in teacher and has done demonstration in fact
It tests, and is applicable in student and does grouping experiment.

(12) upper end tube nozzle of small funnel (10) lower end nozzle and T shape pipe (13) of the connection equipped with wet litmus red test paper (9).T
In beaker (14) of the nozzle insertion in lower end equipped with clarification limewash of shape pipe (13).
The application method of the utility model: suitable ammonium hydrogen carbonate solid (2) is placed on examination by the air-tightness of check device
The bottom for managing (3) is placed on appropriate white copper sulphate solid (5) in the groove of test tube (3) mouth.Gas-guide tube (7) is inserted in
On single hole rubber stopper (6), with single hole rubber stopper (6) stoppered test tube (3) mouth with gas-guide tube (7).Equipped with ammonium hydrogen carbonate solid
(2) it is fixed on the iron stand with iron clamp (4) with the interior reeded test tube (3) of white copper sulphate solid (5), test tube (3) mouth
Slightly tilt down.With the gas-guide tube (7) of the first emulsion tube (8) connection single hole rubber stopper (6) outer end and the side pipe of T shape pipe (13).
Wet litmus red test paper (9) is put into small funnel (10), connects dress with the second emulsion tube (12) with spring clip (11)
There are small funnel (10) the lower end nozzle of wet litmus red test paper (9) and the upper end tube nozzle of T shape pipe (13).In beaker (14)
Dress clarification limewash, in beaker (14) of the lower end nozzle of T shape pipe (13) insertion equipped with clarification limewash, when experiment, opening
Spring clip (11) first gives test tube (3) bottom heating with alcolhol burner (1) flame envelope, after alcolhol burner (1) flame envelope be fixed on be placed with carbonic acid
It heats at the position of hydrogen ammonium solid (2).It can be seen at this time ammonium hydrogen carbonate solid is constantly reduced, white copper sulphate solid gradually becomes
Phenomena such as blue, wet litmus red test paper (9) become blue, clear limewash becomes cloudy, after observing the above phenomenon
Fastening spring presss from both sides (11), and the gas of generation is allowed all to be passed through in clarification limewash, prevents ammonia leakage from polluting air in air.
The reason of above phenomenon occur is that chemical reaction has occurred after ammonium hydrogen carbonate is heated to generate water, ammonia and carbon dioxide gas, raw
At water flow to react in the groove close to test tube mouth with white copper sulphate solid contact and generate the copper sulfate crystal of blue；
Since the density ratio air of ammonia is small, so the ammonia generated is from the upper end tube nozzle of T shape pipe (13) out and in small funnel (10)
Wet litmus red test paper (9) contact, so that wet litmus red test paper is become blue, and the density ratio of carbon dioxide gas
Air is big, contacts so carbon dioxide gas comes out from the lower end nozzle of T shape pipe (13) with clarification limewash, makes to clarify limewash
It becomes cloudy, three kinds of products respectively obtain inspection.The above phenomenon sufficiently proves that ammonium hydrogen carbonate solid has occurred chemical anti-when heated
It answers, generates ammonia gas and water and carbon dioxide gas.The utility model has the advantages that: device is simple, easy to operate, and phenomenon is obvious；Energy
Three kinds of products that ammonium hydrogen carbonate is thermally decomposed are verified respectively, and convincingness is strong；It is safe and environment-friendly pollution-free.It is versatile, both fitted
Lecture experiment is done with teacher, and is applicable in student and does grouping experiment.
