The matter of ammonium water and acetic acid
In the past, there was a wise man, who dedicated himself to studying the nature of things in Shushizhai. The case was placed on ammonium water and acetic acid, in order to explore the combination of the two.

Ammonium water is warm in nature and alkaline in nature. Acetic acid, sour in taste and acidic in nature. The wise man filled the ammonium water in a dish, and poured acetic acid into it. The two touched, like old friends meeting, and suddenly changed.

At first, the bubbles in the liquid were slightly overflowing, as if there was a spirit thing diving. Then, the smell gradually emerged, and the pungent smell of non-ammonium water was not the acidity of acetic acid, but the new taste of the combination of the two was born. Its transformation, molecular fusion, ion coordination, and eventually into a different quality.

The wise man looked at this change and recorded his feelings in detail. Thinking about the combination of the two, although there is no spectacle of fire and smoke, there is a microscopic change, which is the truth of the transformation of heaven and earth. All things in the world have their own nature. They meet and change, or they become new qualities, or they show strange phenomena. This is the beauty of nature. The encounter of ammonium water and acetic acid is but a corner of the change of all things. In the heart of the wise man, it prompts endless thinking. To know the mysteries of nature, you need to pay close attention and study the meaning, so that you can gradually see its path.
