Problems solved by technology

However, the following disadvantages have been found in use: 1) The distance between the two electrodes in the device is large and the communication area is small, and the electrolysis time is relatively long; 2) Water is injected into the long-necked funnel during the experiment, which causes the center of gravity of the device to be high and unstable, and Optional instruments such as heavy iron stand, titration stand, etc. need to be fixed; 3) H 2 It is inconvenient to test, the phenomenon is not obvious, and the test experiment of hydrogen purity in the new textbook cannot be completed; 4) the device cost is high, and it is extremely easy to damage (the parts that are often damaged are: the piston part and the lower end of the upper end of the two glass tubes connected parts)

Abstract

The invention provides a big-belly tank type water electrolysis device and a preparation method thereof. The device comprises a big-belly bulb shaped glass container, wherein, an opening is formed at the upper part of the glass container and two electrodes are arranged at the lower part of the glass container; the two electrodes are connected with an electrolysis power source after extending out of the bottom of the glass container; the bottom of the glass container is sealed with the electrodes; and two gas collecting test tubes respectively buckled on the two electrodes are further arranged in the glass container. The main part of the water electrolysis device provided by the invention, a big-belly tank, is manufactured by completely utilizing a waste bulb which has extensive sources easy to obtain; and the waste is changed into valuables, so that the water electrolysis device is of great benefit to full utilization of the resources, environment protection and experiment cost reduction.

Description

technical field [0001] The invention belongs to the technical field of water electrolysis devices, and relates to a water electrolysis device, in particular to a belly tank type water electrolysis device and a preparation method thereof. Background technique [0002] The water electrolysis experiment is an important enlightenment experiment in the current middle school chemistry textbook. Through the electrolysis experiment of water and the observation, analysis and discussion of the experimental phenomena, it is shown that water is composed of two elements, hydrogen and oxygen. Doing this experiment well is very important for cultivating students' interest in learning chemistry, forming correct concepts of molecules and atoms, and actively participating in experimental exploration. The commonly used device for electrolyzing water in the laboratory is the "Hoffman electrolyzer". The volume ratio of hydrogen and oxygen obtained by electrolyzing water with it is 2:1, which is...
