Abstract
The utility model discloses a mini-type experiment apparatus for carbon to deoxidize copper oxide which comprises a mini-type tube, an alcohol burner, a rubber tube, a right angle bended tube, a mini-type operation table and a small tube. The mini-type tube is fixedly arranged on the mini-type operation table and the tube mouth is slightly inclined in the downward direction. The mini-type tube and the right angle bended tube are connected through the rubber tube. The outlet end of the right angle bended tube is inserted into the small tube. The alcohol burner is arranged on the mini-type operation table which is located right under the bottom of the mini-type tube. The experiment apparatus of the utility model does not cost much to make; simple to make, the apparatus also saves medicine and time. Further, with such an apparatus, a high success rate can be achieved during an experiment. Safe in use, the apparatus is suitable to be adopted in chemical experiments in middle schools.
Description
Technical field
The utility model relates to a kind of middle school chemical experiment device, especially a kind of Reduction of cupric oxide by carbon microscale chemical experiment apparatus.
Background technology
Microminiaturized experiment is to use microminiaturized experimental apparatus, obtain obvious reaction effect and semiochemical a kind of experimental technique with the least possible reagent, adopt microscale experiment to improve chemical experiment teaching, the microminiaturization of experiment, seriation and interest, comprehensive, research are combined together, put forth effort on and cultivate good environmental consciousness, resources consciousness, awareness of safety, the creativity consciousness of student.
About The Experiment of Copperoxide Reducted With Carbon is a very important experiment at middle school period, and student contacts reduction reaction for the first time, significant in whole chemistry learning process.But this experiment difficulty is large, success ratio is lower, and slightly not noting will be failed.Reason has: heating-up temperature is inadequate, sluggish; Reactant ratio is improper; Reactant contact area is less, makes reaction carry out very slow or react not exclusively.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of Reduction of cupric oxide by carbon microscale chemical experiment apparatus is provided, it have equipment cost low, make easily, save medicine and time, and the advantage such as experiment success rate is high, security is good.
For achieving the above object, the utility model adopts following technical proposals:
A kind of Reduction of cupric oxide by carbon microscale chemical experiment apparatus, comprise micro test tube, spirit lamp, rubber tube, quarter bend conduit, miniature operator's console and small test tube, described micro test tube is fixed on described miniature operator's console, the mouth of pipe is slightly downward-sloping, described micro test tube is connected by described rubber tube with described quarter bend conduit, described quarter bend conduit outlet end inserts in small test tube, and described spirit lamp is placed on the described miniature operator's console under described micro test tube bottom.
Described microguide, described quarter bend conduit are made up of same glass tube.
Described micro test tube, described quarter bend conduit all seal.
Described diameter glass tube 4mm, long 20cm.
In described small test tube, fill 2mL saturated limewater solution.
The beneficial effects of the utility model are,
1, microscale experiment instrument draws materials easily, makes simple;
2, microscale experiment phenomenon is more obvious;
3, experimental period is short, and experimental drug amount only has 1/10 of normal experiment, saves medicine;
4, after the evaporation of the moisture in medicine, be condensate in the mouth of pipe and flow out along conduit, reduced the water vapor in pipe, improved success ratio and the security of experiment.
