On the method of formalin-ethyl acetate precipitation

If you want to understand the analysis of matter, you must use the method to improve the technique. There is now a method of formalin-ethyl acetate precipitation (Formalin-ethyl Acetate Sedimentation), which is the key to the analysis of matter. It is the main one. The essence of its method involves a wide range of people.

This method uses formalin and ethyl acetate as the use, and obtains the effect of precipitation. Prepare all things first, carefully measure formalin and ethyl acetate, and combine them in sequence, during which the dynamic and static are connected, and the matter has evolution. Formalin is stable and capable of solid matter; ethyl acetate is volatile and helps sediment. When the two encounter things, the quality of the things should be appropriate. Those who are mixed are divided, and those who are pure are gathered, and they will eventually precipitate, and the work of analyzing the things will be completed.

With this technique, it is advisable to be careful in the operation. At the beginning, the accuracy of the quantity is related to success or failure; at the second, the stirring is moderate, so that the things are uniform; then, wait for it to settle and analyze, and observe it quietly, without disturbing it. In this way, it can be effective, and it will benefit a lot in the matter of analyzing things.

Formalin Ethyl Acetate Sedimentation (Formalin Ethyl Acetate Sedimentation) is a powerful tool for precipitating matter, and it can be used to understand the quality of matter and the mix of matter. It can be used in all karma. Those who are good can do their best.
