Abstract
An experimental device for demonstrating an iron trichloride formation reaction is characterized in that the experimental device comprises a glass tube filled with chlorine gas; openings are formed at two ends of the glass tube; plugs are arranged at the openings; a wire penetrates the glass tube; and the wire can penetrate the plugs in a sliding manner. The opening at one end of the glass tube is larger and sealed with a rubber plug, and the smaller opening at the other end has vaseline applied for sealing; the wire penetrates the rubber plug and the vaseline plug; and a cavity raised outwardly is arranged at the middle part of the glass tube. When in use, the glass tube is filled with chlorine gas at first, then the wire penetrates the glass tube and the tube is sealed; the wire exposed at the small opening end is quickly heated up to a burned red state; when the wire exposed at the small opening is heated to a certain degree, the burned red wire is quickly tightened at the cavity raised inwardly and outwardly of the glass tube from a larger opening end; at a result, the chemical reaction is generated in the glass tube after a few seconds, and the glass tube is filled with tan smog, that is, iron trichloride.
Description
Technical field
The utility model relates to the experimental facilities technical field, the concrete chemical experiment apparatus for demonstrating that relates to a kind of iron and chlorine generation chemical reaction generation ferric trichloride.
Background technology
Chemistry is a laboratory course." halogen " is a chapter in the chemo, but the elementary gas of halogens such as chlorine has penetrating odor and certain toxicity, can produce air pollution in the experimental teaching environment of school.The for example experiment of " iron burns in chlorine " in the chlorine character, the experimental provision on the textbook as shown in Figure 1, the iron wire of heating and chlorine reaction generate tan smog.Teacher generally can be red iron wire heating burning in traditional teaching, opening one bottle of gas bottle that is full of chlorine rapidly, inserts iron wire, covers sheet glass, and iron wire can burn in chlorine like this.
But in experimentation, in any case also can not make gas bottle cover completely, still some chlorine can outwards be revealed.Chemistry teacher and the student who is sitting in the front row can suck many chlorine in respiratory, health is produced injure.
The utility model content
Technical problem to be solved in the utility model is, overcomes problems of the prior art, and a kind of experimental provision of demonstrating the ferric trichloride reaction of formation is provided.
In order to address the above problem the technical solution of the utility model is such:
A kind of experimental provision of demonstrating the ferric trichloride reaction of formation is characterized in that, comprises the glass tube of a splendid attire chlorine, and the glass tube two ends have opening, and opening part has shutoff, is installed with an iron wire in the glass tube, and described iron wire slidably passes shutoff.
Described glass tube one end opening is bigger, the rubber stopper shutoff of this opening; Other end opening is less, and this opening is smeared with vaseline and carried out shutoff; Described iron wire passes rubber stopper shutoff and vaseline shutoff.
Described glass tube middle part has the chamber to outer lug.
During use, be full of chlorine in the glass tube earlier, penetrate the iron wire sealing then, use the iron wire that the osculum end is exposed to be heated to fast and burn red state, when being heated to a certain degree, from big opening end rapidly the chamber that burns in the red iron wire tension glass tube to outer lug, can see, under the state in several seconds, chemical reaction just take place in the glass tube, be full of tan smog in the pipe, i.e. ferric trichloride.
Beneficial effect, experimental provision described in the utility model, it is extremely obvious to have effect, saves reagent, save time, easy to operate advantage, and, help teacher student's health because good sealing effect can not produce classroom environment and pollute.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is existing ferric trichloride reaction of formation experimental provision structural representation;
Fig. 2 is a ferric trichloride reaction of formation experimental provision structural representation described in the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 2
A kind of experimental provision of demonstrating the ferric trichloride reaction of formation, mainly comprise a glass tube 1, glass tube 1 has two ends and has opening, one end opening is called big opening end 11 more greatly, the less osculum end 12 that is called of other end opening, the chamber 13 that the glass tube middle part has a projection adopts drying tube can meet above-mentioned requirements in actual applications.
In glass tube 1, cross one with iron wire 2, glass tube 1 is stretched out at iron wire 2 two ends, the big opening end 11 usefulness rubber stoppers or the cork shutoff of glass tube 1, corresponding iron wire 2 will pass rubber stopper or cork, and iron wire 2 is wanted and can be slided in rubber stopper or cork shutoff.Osculum end at glass tube 1 is coated with the vaseline shutoff, wants that the iron wire 2 of answering also will pass the vaseline shutoff, and iron wire 2 is wanted and can be slided in the vaseline shutoff.
During experiment, be full of chlorine in the glass tube 1 earlier, penetrate iron wire 2 sealings then, use the iron wire 2 that the osculum end is exposed to be heated to fast and burn red state, when being heated to a certain degree, from big opening end rapidly the chamber 13 that burns in the red iron wire 2 tension glass tubes to outer lug, can see, under the state in several seconds, chemical reaction just take place in the glass tube, be full of tan smog in the pipe, i.e. ferric trichloride.
Beneficial effect, experimental provision described in the utility model, it is extremely obvious to have effect, saves reagent, save time, easy to operate advantage, and, help teacher student's health because good sealing effect can not produce classroom environment and pollute.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
