Description
Technical field
The utility model relates to a kind of chemistry experiment device, particularly a kind of conductive electrolyte solution demonstrator of demonstrating conductive electrolyte solution ability power.
Background technology
In the behavior teaching of middle school chemistry material in aqueous solution, often to verify that electrolyte adds the conductive capability of the electrolyte solution that forms in the entry, and judge the power of the conductive capability of various electrolyte solution by experiment.Common way is: get several beakers, inject the volume different electrolyte solutions identical respectively with concentration, in every beaker, insert two carbon electrodes, carbon electrode is fixed on the insulcrete, is cascaded with lead and incandescent lamp, inserts 220 volts of power supplys respectively, observe the bright-dark degree of incandescent lamp, the conductive capability of the electrolyte solution of the explanation correspondence of incandescent lamp amount is strong, otherwise, then a little less than the conductive capability.The shortcoming of this device is: when the conductive capability experiment of doing multiple electrolyte solution, need many covering devices, relatively disperse, be not easy to carry, every covering device need insert power supply respectively, and experiment can not be carried out simultaneously, and need a plurality of supply hubs, increased experimental cost.
Summary of the invention
The purpose of this utility model is to provide a kind of experimental provision to concentrate, be easy to carry, and multiple solution experiments is carried out simultaneously, and supply hub only needs one, lower-cost conductive electrolyte solution demonstrator.
For reaching above purpose, the technical scheme that the utility model adopted is: this conductive electrolyte solution demonstrator, by main body, incandescent lamp, insulcrete, carbon-point, beaker, lead, attaching plug constitutes, it is characterized in that main body is by left plate, right plate, backboard, base plate, fixed head, dividing plate, front apron, side shield connects to one, base plate is located at lower body part, horizontal positioned, front apron, side shield is installed on the base plate, with backboard, left plate, right plate forms the space together, the restriction beaker moves, beaker is placed in the space, and carbon-point is fixed on the insulcrete, and sliding ear is established in the insulcrete left and right sides, left plate, right plate offers chute, sliding ear can slide in chute, and insulcrete and carbon-point move up with sliding ear, and beaker is picked and placeed easily, fixed head is located at main body top, fixing incandescent lamp on it, incandescent lamp separates with the dividing plate that is installed on the fixed head, and the light of incandescent lamp is independent of each other when making experiment.The utility model is also implemented by following measure: the space that base plate, front apron, side shield, backboard, left plate, right plate form is established 3 to 6, the number of corresponding incandescent lamp, beaker is identical with space quantity, it is 3 to 6, the number of carbon-point is the twice of space number, it is 6 to 12, each incandescent lamp, beaker and 2 carbon-points form one group, inject the different electrolyte solution of equal volume and concentration in the beaker respectively, every group of incandescent lamp, carbon-point are connected in parallel after connecting with lead, insert power supply.Observe the light and shade of incandescent lamp, can judge the conductive capability of various electrolyte solutions.
The beneficial effects of the utility model are: this conductive electrolyte solution demonstrator device is concentrated, is easy to carry, and multiple solution experiments is carried out simultaneously, and supply hub only needs one, and cost is lower.
