The method of making acid
There is a technique of making acid in the world, which dissolves hydrochloric acid into ethyl acetate, which is quite exquisite. The degree of hydrochloric acid is often taken as 4mol/L, and this is the key to blending the two to make the phase fuse.
This hydrochloric acid is in ethyl acetate. If it is the main bone, it is the key to acid formation. When operating, when careful to check the ratio of the two, slowly pour hydrochloric acid into ethyl acetate, and keep stirring to ensure that it is uniform.
This liquid is prepared, which can be used for all kinds of things. It can be used as an aid for chemical analysis or as an agent for erosion, and it has a wide range of uses. However, you need to be careful. Hydrochloric acid is strongly corrosive, and ethyl acetate is easy to burn. If you are not careful, the disaster Therefore, the operator should strictly follow the rules and prepare protective equipment to prevent accidents.
This method of acid production can obtain a suitable agent, which is relied on by all karma. Later scholars should also study this technique to make it better and used by the world.
