Abstract

An electric conduction verification demonstrating device of electrolyte solution relates to the technical field of demonstrating devices of experiments of science. The electric conduction verification demonstrating device of the electrolyte solution consists of a U-shaped magnet and U-shaped insulated frames. The two U-shaped insulated frames are parallel to each other, one ends of the two U-shaped insulated frames are fixedly connected through an insulated fixing frame to form a large U-shaped frame, the upper borders of the U-shaped insulated frames are provided with wires, one wire is connected to the positive of a power supply through a switch, the other wire is connected to the negative of the power supply. U-shaped insulated electrolyte containing pipes are hung at the other ends of the two wires, and the wires extend into the U-shaped insulated electrolyte containing pipes. By adding the electrolyte solution to the U-shaped insulated electrolyte containing pipes and electrifying the electrolyte solution, the U-shaped insulated electrolyte containing pipes are capable of moving in the U-shaped magnet so that electrical conductivity of the electrolyte solution is verified. The knowledge of electrochemistry is associated with the knowledge of physical electromagnetics, multiple purposes are realized, phenomena are obvious, and requirements of teachers and thirst and curiosity of students for knowledge are both met. Therefore, the electric conduction verification demonstrating device of the electrolyte solution is a comprehensive science teaching aid which is worth popularizing.

Description

Conductive electrolyte solution checking demonstration device

Technical field

The utility model relates to a kind of natural sciences experimental demonstration device, relates in particular to conductive electrolyte solution checking demonstration device.

Background technology

In science teaching, many classmates hold the suspicious attitude to also there being electric current in the solution, the electrophoresis method checking that the teacher who has adopts, and the electrolyte solution that directly utilizes that also has is demonstrated as the part of circuit, said method needs the time longer, and effect is also not obvious.

The utility model content

The purpose of this utility model is the deficiency that solution is existed the lecture experiment DeGrain of electric current at having now, and a kind of conductive electrolyte solution checking demonstration device is provided.

The purpose of this utility model realizes by following technological means: be made up of U type magnet and U type insulation frame, two U type insulation frames are parallel, one end of two U type insulation frames is fixedly connected to form a large U type frame by the insulation fixed frame, frame above two U types insulation frame is with lead, positive pole that connects power supply by switch wherein, an other negative pole that connects power supply, the other end suspension U type insulation electrolyte of two leads holds pipe, and lead stretches into U type insulation electrolyte and holds in the pipe.

Compared with prior art the utlity model has following tangible advantage: add electrolyte solution and energising in the pipe by holding to U type insulation electrolyte, it can move in U type magnet, verified the electric conductivity of electrolyte solution, galvanochemistry knowledge and physical electromagnetic gained knowledge interrelate, achieve many things at one stroke, phenomenon is obvious, having satisfied teaching requirement and student's aspiration to knowledge, curiosity, is a kind of natural sciences Synthetic educational appliance that promotional value is arranged.
