Reaction observing device used for chemical experiments

Abstract

The invention relates to a reaction observing device used for chemical experiments. The reaction observing device comprises a reaction bottle, a loading sleeve and an end cover, an external thread isarranged on the outer wall of the top of the reaction bottle, an outer sleeve matched with the reaction bottle is arranged on the exterior of the loading sleeve, an internal thread is arranged on theinner wall of the outer sleeve, the loading sleeve is divided into a lower bottle middle segment and an upper connecting segment through the outer sleeve, the lower bottle middle segment is located inthe reaction bottle, a sealing cover which is detachable is arranged at the bottom of the lower bottle middle segment and separated from the lower bottle middle segment under the effect of external force, a ventilating pipe is arranged in the center of the end cover, the top of the ventilating pipe extends out of the top end of the end cover and is connected with a balloon, and the length of theventilating pipe is larger than the height of the loading sleeve. Through the device, the chemical experiments can be conducted in an airtight environment and will not be affected by the environment,in this way, the accuracy of the experiments is guaranteed, meanwhile, the arranged balloon can store gas released in a reaction, and students can conveniently observe the progress of the experiments.

Description

technical field [0001] The invention relates to chemical experiment instruments, in particular to a reaction observation device for chemical experiments. Background technique [0002] Chemistry is a basic course mainly based on experimental science. Chemical experiments are an important part of cultivating students' abilities in independent operation, observation and recording, analysis and induction, writing, reporting, etc. Its main purpose is to verify, consolidate, enrich and improve the important theories and concepts taught by teachers in class, and properly Expand knowledge, train students to correctly master certain experimental operation skills, cultivate students' ability to think independently and work independently, and cultivate students' scientific work attitude and habits. [0003] At present, there are more and more chemical experiment devices. There are various types of experimental devices on the market, but there are still some deficiencies that affect th...

Problems solved by technology

[0003] At present, there are more and more chemical experiment devices. There are various types of experimental devices on the market, but there are still some deficiencies that affect the use of experiments, such as no storage for releasing gases. Device, in the gassing reaction, it is often not easy to observe the experimental process, and some chemical reactions are greatly affected by the environment, and need to be carried out in a sealed environment
