Description
Technical field
A kind of teaching equipment is the utility model is related to, especially a kind of chemistry teaching copper sheet and strong acid reactor.
Background technology
In chemistry teaching, the chemical reaction of concentrated acid and metal provides that experimental demonstration must be carried out in syllabus, greatly
The teacher that part undertakes chemo may require that students ' actual situation operates.Just include two warps by taking the reaction of copper sheet and nitric acid as an example
Allusion quotation is tested：Copper sheet is reacted with concentrated nitric acid：Reaction is fierce, there is the generation of rufous gas；Copper sheet and dilute nitric acid reaction：Produce test tube lower end
Raw colourless gas, gas, which rises, gradually becomes rufous.
It is realized in the prior art：The test tube for filling concentrated nitric acid or dust technology is put into copper sheet, is then observed
.
The prior art is although simple and practical, but there are the defects of be also apparent：The NO or NO2 of generation are reacted first
It is toxic gas, when the experiment is all being done by full class, its concentration produces certain injury to the personnel for participating in teaching, secondly dilute
Nitric acid and the gas color that copper sheet reaction produces are very light, are not easy to laboratory demonstration.
The content of the invention
In view of the deficiencies of the prior art, the utility model provides a kind of safety and is produced easy to observation dust technology and copper sheet reaction
The reactor of angry body color.
The technical solution of the utility model is：
A kind of chemistry teaching copper sheet and strong acid reactor, including dust technology chamber, concentrated nitric acid chamber, it is characterised in that：It is described
Dust technology chamber is connected with concentrated nitric acid chamber, and the dust technology top of chamber is equipped with the first rubber stopper, and first rubber stopper, which is equipped with, to be run through
First copper sheet of the first rubber stopper, the concentrated nitric acid top of chamber are equipped with the second rubber stopper, and second rubber stopper is equipped with through the
Second copper sheet of two rubber stoppers, the dust technology top of chamber side are equipped with exhaust pipe, the concentrated nitric acid top of chamber side be equipped with into
Tracheae, the air inlet pipe are also associated with wind turbine, and the dust technology chamber in the middle part of concentrated nitric acid chamber intersection with being additionally provided with snorkel.
The snorkel is inverted L font, and the upper one end of inverted L font snorkel is connected in the middle part of concentrated nitric acid chamber, and inverted L font is led to
Tracheae lower end thereof is arranged on dust technology bottom of chamber portion but is not contacted with dust technology bottom of chamber portion.
The cotton mass for speckling with sodium hydroxide solution is equipped with the exhaust pipe pipe, its effect is to avoid generated reactive gas from hindering
Evil experimenter.
The dust technology chamber is square container with concentrated nitric acid chamber and is integrated into one, and it is the whole of raising reactor that it, which is acted on,
Body intensity.
White color board is equipped with the outside of the dust technology chamber back side, it, which is acted on, is easy for dust technology and copper sheet from front
React the rufous gas of generation.
The operation principle and method of work of the utility model：
1) pure water is added in dust technology chamber, concentrated nitric acid is added in concentrated nitric acid chamber；
2) two rubber stoppers are covered, and two copper sheets are filled in into simultaneously contact liq；
3) dense rufous is presented in concentrated nitric acid chamber reaction generation NO2, opens wind turbine；
4) the rufous gas of concentrated nitric acid intracavitary is passed through in the pure water of dust technology intracavitary；
5) pure water become dust technology and with copper sheet react generation colourless gas (bubble), the gas after liquid is left on
Rise and slowly become light brown red.
The beneficial effects of the utility model are：The utility model is designed reasonably, reacts for half-sealed, largely there is poison gas
Cognition is disposed off, and color board is used so that observing more convenient, and finally also reducing the use of nitric acid, (dust technology is to be passed through
Generated after reacting gas).
