Pollute.
The purpose of this utility model realizes by the following method:
A kind of experimental provision confirming ammonium fertilizer and alkali Hybrid Heating generation ammonia, is primarily characterized in that: it is by carrying
The iron stand (1) of iron clamp (2), tool equipped with ammonium sulfate (4) prop up test tube (3), the first rubber closure (5), equipped with sodium hydroxide solution
Glue head dropper (6), latex tubing (7), drying tube (9) equipped with moistening litmus red test paper (8), the second rubber closure (10),
Airway (11), the beaker (12) equipped with dilute sulfuric acid, alcohol burner (13) composition.
Prop up test tube (3) equipped with the tool of ammonium sulfate (4) to be fixed on the iron stand (1) of band iron clamp (2), band glue head dropper (6)
The first rubber closure (5) stopper the mouth of pipe of tool test tube (3).Latex tubing (7) connects the arm of tool test tube (3) and equipped with moistening
Less that end mouth of pipe of the drying tube (9) of litmus red test paper (8).Second rubber closure (10) of band airway (11) stoppers dry
That end mouth of pipe that dry pipe (9) is bigger, the end of airway (11) stretches in the beaker (12) equipped with dilute sulfuric acid.Alcohol burner (13) is put
Put in the lower section heating of tool test tube (3).
Experimentation: connect instrument, checks the air-tightness of device.Moderate amount of sulfuric acid ammonium is put in tool test tube (3), use
Sodium hydroxide solution drawn by glue head dropper (6) with the first rubber closure (5), then with the first rubber closure of band glue head dropper (6)
(5) stopper the tool equipped with ammonium sulfate (4) and prop up test tube (3) mouth of pipe.With iron clamp (2), tool test tube (3) is fixed on iron stand (1)
On.Moistening litmus red test paper (8) is put in drying tube (9), with latex tubing (7) connect tool test tube (3) arm and
Equipped with that end mouth of pipe that the drying tube (9) of moistening litmus red test paper (8) is less.The second rubber closure with band airway (11)
(10) that end mouth of pipe that the drying tube (9) equipped with moistening litmus red test paper (8) is bigger is stoppered, the end of airway (11)
Stretch in the beaker (12) equipped with dilute sulfuric acid.During experiment, the Rubber end of extruding glue head dropper (6), make the hydrogen in glue head dropper (6)
Sodium hydroxide solution instills in tool test tube (3) and contacts with ammonium sulfate (4), then lights alcohol burner (13), by alcohol burner (13)
The bottom-heated of flame envelope alignment tool test tube (3), it can be seen at this time produce bubble, in drying tube (9) in tool test tube (3)
Moistening litmus red test paper (8) becomes blueness.This is because sodium hydroxide solution is given birth to after mixing with ammonium sulfate in a heated condition
Having become ammonia, ammonia to contact with moistening litmus red test paper (8), moistening litmus red test paper (8) becomes blueness, above phenomenon
Fully prove that ammonium fertilizer and alkali heat altogether creates ammonia.Unnecessary ammonia enters equipped with in the beaker (12) of dilute sulfuric acid, therefore
Eliminate pollution.
The beneficial effects of the utility model are: demonstrate the experiment of ammonium fertilizer and alkali Hybrid Heating with this utility model, by
Carry out in hermetic container in reaction, so very environmental protection；This utility model highly versatile, had both been suitable on classroom and had drilled
Show experiment, be suitable for again student and do grouping experiment.
Four, accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Labelling in figure represents respectively:
(1) iron stand (2) iron clamp (3) tool test tube (4) ammonium sulfate (5) first rubber closure (6) is equipped with sodium hydroxide
