Abstract
The utility model provides the environment-friendly type experimental provision of a kind of ammonia and hcl reaction, is primarily characterized in that: it props up test tube (1) by tool, rubber stopper with double hole (2), spring clamp one (3), the syringe (4) that hydrogen chloride is housed, balloon (5), spring clamp two (6), the syringe (7) that ammonia is housed, short-range missile tracheae one (8), short-range missile tracheae two (9) form.Spring clamp one (3) is first opened during experiment, touch syringe (4), allowing appropriate hydrogen chloride enter tool, to prop up test tube (1) inner, then spring clamp two (6) is opened, touch syringe (7), allow appropriate ammonia enter tool and prop up that test tube (1) is inner to be mixed with hydrogen chloride, two kinds of gases prop up in test tube at tool and chemical reaction occur, produce a large amount of white cigarettes, tool props up on test tube (1) inwall and adheres to white solid.This device is not only applicable to classroom does lecture experiment, but also is applicable to student and does grouping experiment, saves medicine, and can reduce environmental pollution.
Description
technical field
the utility model belongs to chemical field, relates to a kind of chemical experiment device, particularly for demonstrating the experiment of ammonia and hcl reaction on middle school chemistry textbook.
background technology
ninth grade chemistry textbook the 12nd page of ammonia that Shanghai in January, 2012 education publishing house publishes and the Interesting Tests of hcl reaction, in two gas bottles, ammonia and hydrogen chloride are housed respectively, relatively make two bottles of gas and vapor permeation chemical reaction occur two gas bottle bottlenecks together, in bottle, produce a large amount of white cigarettes.Operate like this in the teaching material also had: dip in strong aqua and concentrated hydrochloric acid respectively with two glass bars, then by these two glass bars close to (not contact).Although the method in teaching material is simple, convenient, phenomenon is obvious, ignore ammonia that strong aqua volatilizes to the spread effect of the mucous membrane of human eye, nose, larynx, and hydrogen chloride is to the harm of human body.Improve the experimental provision of existing ammonia and hcl reaction, make the device environmental protection after improvement, no longer include above defect.
utility model content
the utility model object is the environment-friendly type experimental provision providing a kind of ammonia and hcl reaction, makes device not be only applicable to classroom does lecture experiment, but also is applicable to student and does grouping experiment, and can reduce environmental pollution.
the purpose of this utility model realizes by the following method:
the environment-friendly type experimental provision of ammonia and hcl reaction, is primarily characterized in that: it props up test tube (1) by tool, rubber stopper with double hole (2), spring clamp one (3), the syringe (4) that hydrogen chloride is housed, balloon (5), spring clamp two (6), the syringe (7) that ammonia is housed, short-range missile tracheae one (8), short-range missile tracheae two (9) form.
rubber stopper with double hole (2) is plugged short-range missile tracheae one (8), short-range missile tracheae two (9) respectively, the short-range missile tracheae two (9) of rubber stopper with double hole (2) outer end is fixed a balloon (5), air in balloon (5) and tool prop up the air communication in test tube (1), and balloon (5) plays depressurization.At a bit of emulsion tube of the upper connection of rubber stopper with double hole (2) outer end short-range missile tracheae one (8), clamp emulsion tube with spring clamp one (3), the syringe (4) that hydrogen chloride is housed is connected with emulsion tube; Tool prop up test tube (1) left side arm on connect a bit of emulsion tube, with spring clamp two (6) clamp emulsion tube, the syringe (7) that ammonia is housed is connected with emulsion tube.
experimentation: connect instrument, the impermeability of testing fixture, spring clamp one (3) is first opened during experiment, touch syringe (4), allowing appropriate hydrogen chloride enter tool, to prop up test tube (1) inner, then opens spring clamp two (6), touch syringe (7), allow appropriate ammonia enter tool and prop up that test tube (1) is inner produces a large amount of white cigarettes with hydrogen chloride generation chemical reaction, tool props up on test tube (1) inwall and adheres to white solid.
the beneficial effects of the utility model are: the experiment demonstrating ammonia and hcl reaction with the utility model, can control the amount of reactant, save medicine.Again because reaction is carried out, so decrease environmental pollution in closed container; The utility model highly versatile, had both been suitable on classroom and had done lecture experiment, was suitable for again student and did grouping experiment.

1. tool prop up test tube 2. rubber stopper with double hole 3. spring clamp one 4. hydrogen chloride is housed syringe 5. balloon 6. spring clamp two 7. the syringe 8. short-range missile tracheae one 9. short-range missile tracheae two of ammonia is housed
embodiment
below in conjunction with embodiment, the utility model is described in further detail:
the environment-friendly type experimental provision of ammonia and hcl reaction, is characterized in that: it props up test tube (1) by tool, rubber stopper with double hole (2), spring clamp one (3), the syringe (4) that hydrogen chloride is housed, balloon (5), spring clamp two (6), the syringe (7) that ammonia is housed, short-range missile tracheae one (8), short-range missile tracheae two (9) form.
rubber stopper with double hole (2) is plugged short-range missile tracheae one (8), short-range missile tracheae two (9) respectively, the short-range missile tracheae two (9) of rubber stopper with double hole (2) outer end is fixed a balloon (5), air in balloon (5) and tool prop up the air communication in test tube (1), and balloon (5) plays depressurization.At a bit of emulsion tube of the upper connection of rubber stopper with double hole (2) outer end short-range missile tracheae one (8), clamp emulsion tube with spring clamp one (3), the syringe (4) that hydrogen chloride is housed is connected with emulsion tube; The arm that tool props up on the left of test tube connects a bit of emulsion tube, clamps with spring clamp two (6), the syringe (7) that ammonia is housed is connected with emulsion tube.
using method of the present utility model: connect instrument, the impermeability of testing fixture, spring clamp one (3) is first opened during experiment, touch syringe (4), allowing appropriate hydrogen chloride enter tool, to prop up test tube (1) inner, then opens spring clamp two (6), touch syringe (7), allow appropriate ammonia enter tool and prop up that test tube (1) is inner to be mixed with hydrogen chloride, two kinds of gases prop up at tool and in test tube, chemical reaction occur and produce a large amount of white cigarette, and tool props up on test tube (1) inwall and adheres to white solid.The experiment of ammonia and hcl reaction is demonstrated, because the amount of reactant can be controlled, so medicine can be saved, again because reaction is carried out, so decrease environmental pollution in closed container with the utility model; The utility model highly versatile, had both been suitable on classroom and had done lecture experiment, was suitable for again student and did grouping experiment.
