The Separation of Barium Nitrate and Sodium Acetate
Over the years, some scholars have studied the transformation of various pharmaceuticals in sequence. One day, I wanted to explore the change of the mixing of Barium Nitrate and Sodium Acetate.

Take an appropriate amount of barium nitrate liquid and place it in a purifier. The liquid is clear and clear, free of impurities and dross. Take the solution of sodium acetate again, and slowly pour it into the barium nitrate liquid. In an instant, I see things gradually dissolve, like dust at the beginning, floating in the liquid, and then phase and meet, gradually forming precipitation (Precipitate), its color is pure and white, just like new snow falling between waves.

The scholar stared at this scene, and his heart was very different. After thinking about it, when barium nitrate meets sodium acetate, the ionic phase is easy, and insoluble substances are produced, which leads to precipitation. Although this is a small matter, in the field of chemistry, it is the important way to explore the transformation of things. From this, it can be seen that the sympathetic substances follow their own laws, and subtle observations can open the door to chemical arcane.
