Abstract
The utility model relates to an electrolyte solution electric conduction demonstrating instrument, relating to an improved utility model of a chemical teaching aid. The demonstrating instrument makes various experiment components used for original experiments assembled on a table plate bracket, uses an alternating current power supply to replace the original direct current power supply, uses bulbs for indicating and simultaneously is additionally provided with a galvanometer index for displaying the conductance strength of the electrolyte solution to prevent the acid liquor from overflow. In order to fix the position of electrodes, the opening of a beaker is additionally provided with a flexible plug. The consistency of and the observe effect of the demonstration of each group of experiment conditions are intensified. Consequently the utility model is convenient in carry over, convenient in operation, saving in experiment time, obvious in contrast effect of observe and good in effect of teaching.
Description
Conductive electrolyte solution demonstrator of the present utility model relates to the chemistry teaching teaching aid.
The known lecture experiment about the conductive electrolyte solution situation is continued to use apparatus for demonstrating shown in the middle school chemistry textbook, form by electric battery, lead, bulb, beaker and various electrolytic solution, the conduction situation is not easily distinguishable in the various electrolyte solutions, it is more that each experiment connects the lead spended time, electrode is difficult for fixing in beaker, operating performance is numerous and diverse, work accident easily takes place, the experiment emphasis is not outstanding, energy disperses during observation of students, be difficult for grasping the experiment emphasis, thereby teaching efficiency is not ideal.
The purpose of this utility model is to propose a kind ofly clearly to show the demonstrator of conductive electrolyte solution situation and design and produce scheme, make the student can image, directly perceived, the conduction situation of comparatively observing various electrolyte solutions arranged.
Conductive electrolyte solution demonstrator of the present utility model will be tested required bulb, galvanometer, parts etc., all assemble and be fixed on the vertical shelf, both can save numerous and diverse operating performance, be convenient to the student again and concentrate one's energy, the observation experiment main points, thus the experimental observation effect improved greatly; The beaker of splendid attire electrolyte solution seals with soft plug, both can prevent that acid, alkaline electrolyte from overflowing, but fixed electorde position again needn't be adjusted temporarily again; Security and the convenience manipulated for increase; this demonstrator is provided with protective tube, earth leakage protective device and branch switch; for increasing the demonstration effect of each conductive electrolyte solution situation; except that adopting AC power to replace the original battery dc group, also set up the reometer that shows each conductive electrolyte solution intensity.
Accompanying drawing 1 is a floor map of the present utility model:
The splendid attire homogenous quantities is with on five beakers (10) of five kinds of electrolyte solutions (9) of concentration base that is placed on Plate support (11) equidistant in one line, installing etc. the soft plug (7) of the electrode (8) that equates of resistance, die opening clog beaker (10) rim of a cup respectively, AC power cord is connected on respectively on each electrode cable (6) by master switch (1), fuse (2), bulb (3), galvanometer (4) and branch switch (5).
When demonstration is used, open master switch and each branch switch, energized, various electrolyte have shown the difference conduction situation of different electrolyte solutions under the same conditions according to the different pointer range visual patterns ground of different brightness of bulb and reometer.
This device is respectively tested components and parts with former experiment usefulness, and combination is contained on the Plate support, and strengthens and respectively organize the consistance of experiment condition and the observing effect of demonstration, easy to carry, save operation time, comes into plain view, and teaching efficiency is obvious.This device through after the alternating current-direct current rectification, can also carry out electrolysis at power supply, the demonstration of the principles of chemistry such as platings, suitable just, senior middle school and university chemistry education experiment usefulness.
Claims (3)
1, a kind of conductive electrolyte solution demonstrator is made of utility appliance such as electrolyte solution, demonstration bulb, galvanometer, Plate supports; the beaker that it is characterized in that bulb, galvanometer, branch switch, earth leakage protective device, switch and electrolyte-electrode and the various electrolyte solutions of splendid attire all installs on Plate support; and after connecting respectively, terminate in the power circuit.
