Abstract

The utility model discloses a salt solution and cupric chloride dihydrate electrolyser used for teaching, which is composed of a base. Both sides of the upper end of a U-shaped tube are respectively provided with an L-shaped gas guiding branch tube communicated with the U-shaped tube. The solution is the U-shaped tube is electrolyzed in an experiment, generated gas is guided out by the two gas guiding branch tubes, and chlorine gas is guided into a small test tube by a rubber tube connected with the gas guiding branch tubes. The utility model has the advantages of simple structure and convenient use. The environmental pollution caused by harmful gas is eliminated, and teachers and students' health is guaranteed.

Description

Salt solution, cupric chloride electrolyzer

Technical field

The utility model relates to a kind of salt solution, cupric chloride electrolyzer.Be specially adapted to fields such as school instruction and chemical scientific research.

Background technology

According to the 3rd (required adding takes as an elective course) middle regulation of senior middle school's chemistry teaching material that write existing People's Education Publishing House, the experiment of electrolysis saturated aqueous common salt, electrolytic chlorination copper solutions is teacher's lecture experiment.The new addendum of its electrolysis saturated aqueous common salt is a student experiment in group.Electrolyzer shown in the teaching material belongs to teacher's Self-made Realia, its shortcoming is: the part parts of electrolyzer need teacher oneself to solve, and prepare the loaded down with trivial details time-consuming of test, and experimental installation assembles built on the sand, experiment effect is poor, and three kinds of products that experiment generates can only be checked out wherein two kinds.And the obnoxious flavour (chlorine) that is generated during experiment at will is emitted in the classroom, contaminate environment, and the infringement teachers and students' is healthy.

Summary of the invention

For the many weak points of the promise that overcomes above-mentioned experimental installation, the experiment of electrolysis saturated common salt power and water Cupric Chloride Solution is done better, by test of many times and improvement, develop a kind of salt solution, cupric chloride electrolyzer.

The utility model is realized with following technical scheme: this experimental installation comprises a base, U type pipe.Respectively there is an air-guide branch pipe that is communicated with U type pipe the upper end of U type pipe, and air-guide branch pipe is the  type.During experiment,, will insert U type pipe two ends with the Graphite Electrodes of plug again, connect power supply, make solution generation electrolysis in the U type pipe when the U type pipe saturated aqueous common salt of packing into.The gas of its generation is drawn by two air-guide branch pipes.The anodal chlorine that produces promptly with in the alkaline solution in the sebific duct introducing small test tube of air-guide branch pipe connection, prevents to leak after check.The hydrogen that negative pole produces is collected check by small test tube, and sound hears a scream.It is red that U type pipe negative pole one side solution shows.Three kinds of products in the experiment all are verified.The thick about 2mm of the base of this device, the centre has 2 Baltimore grooves.One can be inserted its groove for U type pipe.Another can place the conduction supply lead.Respectively there is a circular hole base concave groove both sides, can supply the small test tube socket.

Positively effect of the present utility model is: simple in structure, easy to use, eliminated harmful gas pollution, the health that helps protecting environment and ensure numerous teachers and students.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing 1 is the electrolyzer structural representation.

Accompanying drawing 2 is a base vertical view.

In the accompanying drawing 1,1, U type pipe, 2, the Graphite Electrodes of band plug, 3, power lead, 4, small test tube, 5, air-guide branch pipe, 6, base, 7,8, groove, 9, circular hole.

Embodiment:

With reference to accompanying drawing, U type pipe (1) is placed in the groove of base (6), and there are two little air-guide branch pipes (5) both sides, upper end of U type pipe (1).During experiment, when packing salt in the U type pipe, will insert U type pipe with the Graphite Electrodes of plug again, connect power supply, make solution generation electrolysis in the U type pipe.The gas of its generation is drawn by airway (5), in the alkaline solution in the sebific duct introducing small test tube (4) that the anodal chlorine that produces is connected by air-guide branch pipe (5) after checking, prevents to leak.The hydrogen that negative pole produces is collected check by small test tube (4), and sound hears a scream.It is red that U type pipe negative pole one side solution shows.Three kinds of products in the experiment all are verified.

Claims

1, a kind of salt solution, cupric chloride electrolyzer is characterized in that comprising a base (6), are inserted in U type pipe (1) on the base, and respectively there is an air-guide branch pipe (5) that is communicated with U type pipe the upper end of U type pipe, can insert the Graphite Electrodess (2) of 2 band plugs of U type pipe in addition.Be provided with the groove (7) that can insert U type pipe in the middle of the base, can place the groove (8) of conduction supply lead, a circular hole (9) is respectively arranged in the groove both sides.
