Abstract
The utility model discloses a multi -functional chemistry experiment device, this chemistry experiment device include mainly that impregnator, test tube, two -way point chew the return bend, the impregnator passes through the pipe and links to each other with the test tube, the one end of chewing the return bend with two -way point again suitable for reading of test tube links to each other, two -way point is chewed and is equipped with a stagnant water on the return bend and presss from both sides. Owing to adopt above -mentioned structure, the device experiment function is many, demonstrate effectual, simple structure, convenient operation moreover.
Description
Technical field
The utility model belongs to technical field of teaching instruments, particularly relates to a kind of Multifunctional chemical experiment device.
Background technology
Chemical experiment is the important component part of chemistry teaching, due to it have vividly, intuitive, teacher is easily said, student is understandable easy to learn, thus improve quality of instruction and accelerate teaching process, and the quality of experimental provision design, be again test whether successfully one of key factor, therefore select rational experimental provision particularly important.Present experiment device for teaching ubiquity function singleness, the problem of demonstrating visual's property difference, not only affects quality of instruction, also increases expenditure, wastes medicine, contaminated environment, and we devise a kind of Multifunctional chemical experiment device for this reason.
Summary of the invention
The purpose of this utility model is to provide one and has multi-functional chemical experiment device.
The purpose of this utility model is achieved through the following technical solutions, this chemical experiment device mainly comprises impregnator, test tube, two-way point chew bend pipe, described impregnator is connected with test tube by conduit, one end of chewing again bend pipe with two-way point suitable for reading of described test tube is connected, and described two-way point is chewed bend pipe and is provided with a tongs.
Note before using checking impermeability, to guarantee the sealing of junction, this experimental provision has the function of general gas flow generator, can prepare following several gas:
(1) MnO is loaded in test tube
2(or NaCl) solid, injects H by impregnator
2o
2(or H
2o), oxygen can be obtained.
(2) MnO is loaded in test tube
2, inject concentrated hydrochloric acid by impregnator, more slightly heat, can chlorine be obtained.
(3) Na is loaded in test tube
2sO
3(or NaCl), injects dense H by impregnator
2sO
4, sulphuric dioxide (or hydrogen chloride) gas (the latter needs heating) can be obtained.
(4) dense H is loaded in test tube
2sO
4, inject formic acid by impregnator, can carbon monoxide be obtained.
(5) load calcium carbide in test tube, slowly instill water or saturated aqueous common salt by impregnator, steady, uniform acetylene gas can be obtained.
The beneficial effects of the utility model are: not only structure is simple, easy to operate, and function is many, and experiment effect is good.
Accompanying drawing explanation
