Abstract
The utility model relates to enclosed reaction equipment of ammonia gas and hydrogen chloride. The reaction equipment is composed of two syringes, two wide-mouth bottles and a tripartite ball. The wide-mouth bottles and a bottleneck of the tripartite ball are provided with foraminous rubber plugs. The syringes and the wide-mouth bottles are connected through conduits. The wide-mouth bottles are also connected with the tripartite ball through conduits. The conduits are provided with switches. As the whole experiment of the utility model is carried out in an enclosed state, the enclosed reaction equipment is environmentally friendly and is convenient to operate, and the experiment effect is visual and obvious.
Description
One, technical field
The utility model relates to a kind of chemistry teaching equipment, especially a kind of closed ammonia and hcl reaction device.
Two, background technology
This lecture experiment of experiment 2 " ammonia and hcl reaction " that Shandong version regular senior secondary school in 2007 chemistry 1 is required the 77th page, be designed to " in two gas bottles, splash into several strong aquas and concentrated hydrochloric acid respectively; cover glass sheet; the glass sheet in the middle of taking out then, observe the phenomenon that takes place " on the teaching material.And write " in strong aqua and concentrated hydrochloric acid, dip in respectively with two glass bars, then with two glass bars near (contact), the phenomenon of observing generation " on other version chemistry textbook.During according to the operation of this method, classmates can see two glass bars near the time, produce a large amount of white cigarettes and be diffused in the air rapidly.As everyone knows, ammonia has spread effect to mucous membranes such as people's eye, nose, larynxs, and hydrogen chloride has the strong impulse smell, and these two kinds of gases are heavy contaminant, and the people is in case suck, even amount is little, all can cause in various degree influence to health.In addition, they also exist problems such as inconvenient operation, experiment effect be not directly perceived, not obvious.
Three, summary of the invention
The purpose of this utility model provides a kind of closed ammonia and hcl reaction device, and ammonia and hcl reaction carry out under air-tight state, can overcome the problems referred to above that prior art exists.
The technical scheme that the utility model is taked is:
It is made of 2 syringes, 2 wide-necked bottles and 1 three ball, and described wide-necked bottle and three pin mouths are provided with plug with holes; Described syringe is connected by conduit with wide-necked bottle; Described wide-necked bottle is connected by conduit with three balls again, and conduit is provided with switch.
Catheter tip in described three balls is bending.
Because the whole experiment of the utility model is carried out under closed state, so than environmental protection; During experiment, 2 wide-necked bottles are equipped with strong aqua and concentrated hydrochloric acid respectively, and pushing syringe can splash into two kinds of reactants in three balls, and is easy to operate; Ammonia and hcl reaction are in transparent container, and experiment effect is directly perceived, obvious.
Four, description of drawings
Concrete structure of the present utility model is provided by the following drawings.
Fig. 1 is structural representation of the present utility model.
Sign in the accompanying drawing is represented respectively:
1. syringe 2. switches 3. conduits 4. 3 balls 5. wide-necked bottles 6. plugs with holes
Five, embodiment
As can be seen from Figure 1, the utility model is made of 2 syringes 1,2 wide-necked bottles 5 and 1 three ball 4, and described wide-necked bottle 5 and three balls, 4 bottlenecks are provided with plug 6 with holes; Described syringe 1 is connected by conduit 3 with wide-necked bottle 5; Described wide-necked bottle 5 is connected by conduit 3 with three balls 4 again, and conduit 3 is provided with switch 2; Conduit (3) end in described three balls (4) is bending.
When doing experiment, 2 wide-necked bottles 5 are respectively charged into strong aqua and concentrated hydrochloric acid, cover plug 6 with holes, open the switch 2 on the conduit 3, promote injection, and 1 can splash into two kinds of reactants in three balls 4.Because conduit 3 ends are bending, liquid just can accurately drip in the ball of limit, and hydrogen chloride gas and ammonia react in closed container, has a large amount of white cigarettes to produce, and inwall has the chloride solid of a large amount of whites to adhere to.
Claims (2)
1. a closed ammonia and hcl reaction device is characterized in that it is made of 2 syringes (1), 2 wide-necked bottles (5) and 1 three ball (4), and described wide-necked bottle (5) and three balls (4) bottleneck are provided with plug with holes (6); Described syringe (1) is connected by conduit (3) with wide-necked bottle (5); Described wide-necked bottle (5) is connected by conduit (3) with three balls (4) again, and conduit (3) is provided with switch (2).
2. closed ammonia according to claim 1 and hcl reaction device is characterized in that conduit (3) end in described three balls (4) is bending.
