The three-purpose test instrument for electrolysis, electroplating and galvanic cell has compact structure, convenient operation, clear experiment phenomenon and theory and short reaction time, the effect of experiment can be enhanced, and the three-purpose test instrument for electrolysis, electroplating and galvanic cell can be utilized for popularizing chemical fundamental knowledge for countrywide middle school students.
Description
The utility model relates to a kind of education or demonstration equipment, particularly chemical experimental apparatus.
The teaching of fiting chemical class electrolyte solution need be carried out electrolysis, plating, three student experimentings of primary element.Experiment at present is to carry out on the different experimental facilities of three covers.Carrying out electrolytic experiment is to carry out in a U-shaped pipe, and the U-shaped pipe is erected on the iron stand by cross clamp, adds CuCl in the U-shaped pipe
2Solution inserts two carbon-points respectively in two pipes of U-shaped pipe, with direct supply 220 volts of alternating currents are become direct current about 10 volts, and positive and negative electrode is connected respectively on two carbon-points.After the energising, can see having mauve copper to generate on the negative carbon, moistening starch--the KI test paper stretches into the anodic site, can see that test paper becomes blue purple, proves Cl

2↑.Electroplating experiment is to add electroplate liquid in glass jar or beaker, and the edge of glass jar hangs up zinc metal sheet, traverse one glass rod on the glass jar, and glass rod hangs up plating piece with a hook down.With direct supply 220 volts of alternating currents are become 2 volts of left and right sides direct currents, positive pole and zinc metal sheet, negative pole can plate the zinc of one deck grey black gradually with after plating piece links to each other on the visible plating piece, the principle and the process of electroplating with explanation.Carrying out the primary element experiment is to put into dilute sulfuric acid in beaker, and zinc metal sheet and copper sheet are separately inserted beaker, and visible zinc metal sheet surface has bubble to produce, and copper sheet is reactionless.After being connected to zinc metal sheet and copper sheet on the galvanometer with lead, visible galvanometer needle deflection, the copper sheet surface has bubble to produce.This explanation zinc loses electronics and becomes zinc ion, and its electronics flows to copper sheet by lead, and hydrogen ion is surperficial that electronics generates hydrogen at copper sheet.This experimental provision is by general test device group and forms, do electrolysis, must in classroom that AC Power supply socket is arranged or laboratory, carry out when electroplating experiment, and must every group all be furnished with direct supply and carry out transformation and rectification, this is not having in the simple and crude school of laboratory or appointed condition, is difficult to realize.In addition, because device and circuit all are to gather to connect temporarily, be easy to the both positive and negative polarity contact is caused " short circuit ", burn fuse, the teacher has to be busy with changing fuse, influences teaching efficiency.The alkali wash water that uses in the experiment, passivating solution have very strong corrosivity, often are dropped on the lead, on the direct supply, easily make its damage.
The purpose of this utility model is the instrumentation that provides a kind of electrolysis, plating, the experiment of primary element three usefulness, do not need 220 volts alternating current and direct supply, thereby can and not have under the condition of the various general experiment apparatus of quantity in cold backcountry, manipulate for Faculty and Students, because apparatus structure is more fixing, therefore also overcome the existing shortcoming of above-mentioned existing experiment apparatus.
Accompanying drawing 1 is a structural representation of the present utility model, and Fig. 2,3,4,5 is indispensable annex.1 is battery case among the figure, and 2 are the experiment cylinder, and 3 is carbon-point, and 4 is geometrical clamp, and 5 is mobile window, and 6 is division board, and 7 is the copper wire hook, and 8 is plating piece, and 9 is zinc metal sheet, and 10 is copper sheet, and 11 is top cover.
The utility model adopts the dc source of two 1.5 volts of batteries series connection, chemical reaction is to carry out in the closed container of experiment cylinder and top cover composition, being electrically connected all is fixing structure, with wallboard they are separated in the middle of the housing that battery case 1 and experiment cylinder 2 form, experiment cylinder 2 is the container of a sealing, do not allow liquid to leak from cylinder, battery case 1 is located at the outside of experiment cylinder; Be provided with a top cover 11 above the housing, be fixed with two fixing folders 4 on the top cover, below the opening place of fixing folder 4, have through hole on the top cover, top cover 11 can be on housing arbitrarily dismounting, mobile window 5 also is housed on the top cover 11, it can be on top cover 11 arbitrarily dismounting, the centre of experiment cylinder 2 is provided with isolation plate 6.
Provide embodiment of the present utility model in conjunction with the accompanying drawings.
Make with transparent, acidproof, material by the housing that battery case 1 and experiment cylinder 2 are formed, be a rectangular parallelepiped, middle for testing cylinder, the left and right sides is a battery case, respectively put 1.5 volts of No. 1 batteries of a joint in the box, two batteries are connected in series, and are provided with contact in the box bottom, and connect with lead, the top directly links to each other with geometrical clamp 4 with spring leaf, separate with dividing plate between battery case 1 and the experiment cylinder 2, make 2 one-tenth one airtight containers of experiment cylinder, installing and locating in the groove that top cover 11 embeds on the housing.When carrying out electrolytic experiment, be moved to the left and open top cover 11, in experiment cylinder 2, inject CuCl
2Solution covers top cover, and two carbon-points 3 respectively by inserting experiment cylinder 2 in the through hole of top cover, and are clipped with geometrical clamp 4, and it is suspended on the solution in the cylinder, can carry out electrolytic experiment after putting into two batteries and connecting battery.After two minutes, open mobile window 5, stretch into moistening starch-KI test paper, can record test paper and be bluish violet, prove Cl
