Electrolytic saltwater device for laboratory

Abstract

The invention discloses an electrolytic saltwater device for a laboratory and mainly relates to the field of chemical experiment instruments. The electrolytic saltwater device for the laboratory comprises a supporting seat; a supporting column is arranged at the top of the supporting seat; a slide block is arranged on the supporting column; supporting cross rods are symmetrically arranged at the top of the supporting column; supporting frames are arranged at one ends of the supporting cross rods; fixing rods are arranged at the lower parts of the supporting frames; supporting circular rings are arranged at one ends of the fixing rods; movable rods are arranged on the upper sides of the fixing rods; rubber plugs are arranged at one ends of the movable rods; electrodes are arranged on the rubber plugs. The electrolytic saltwater device for the laboratory, disclosed by the invention, has the advantages that the electrodes can be firmly fixed and the lead can be arranged within the supporting column and the supporting cross rods; therefore the leads can be prevented from being scattered on an experiment table, the clean and orderly experiment table can be guaranteed, the smooth performing of the experiment can be guaranteed, potential safety hazards in the experiment process can be reduced, the chlorine in the experiment process can be effectively absorbed and treated, and the chlorine can be prevented from directly entering the air.

Description

technical field [0001] The invention relates to the field of chemical experiment equipment, in particular to a laboratory electrolysis salt water device. Background technique [0002] Electrochemistry is a science that studies the relationship between electricity and chemical reactions. Electrolysis of salt water is a classic case for learning the principles of electrochemistry, which is of great significance in teaching. At present, when performing electrolysis salt water experiments in the laboratory, the salt water is usually added to the U-shaped tube, and copper electrodes and graphite electrodes are respectively placed at both ends of the U-shaped tube. The electrodes are often directly inserted into the U-shaped tube, and the electrodes are very It is difficult to fix firmly, and the wires connecting the electrodes and the DC power supply are scattered on the test bench, which brings certain troubles to the experiment and also brings certain safety hazards. The chlori...
