The matter between lead and acetic acid
Lead is heavy in nature and heavy in quality. It used to be used in craftsmanship in the past. At that time, people gradually noticed the nature of lead.

One day, a craftsman used lead to enter acetic acid. Acetic acid is acidic and corrosive. When lead encounters acetic acid, it is quiet at first, and not long after, its surface gradually changes, as if something is hidden.

But the body of lead, under the erosion of acetic acid, slowly melts. The two intersect and produce new compounds. The shape of the compound is different from that of lead and acetic acid, and its properties also change.

The craftsman looked at it and thought about the beauty of chemistry. The combination of lead and acetic acid is not a change of solitary form, but a transformation of nature. People in future generations should study this kind of combination in detail, or they can obtain many benefits, so that they can be used for all kinds of things, to improve the advantages and eliminate the disadvantages, and to seek well-being for people's livelihood.
