Chemical response
In the past, there were warlocks who were skilled in chemical techniques. One day, he wanted to use potassium chromate and lead acetate as materials to seek a wonderful change.

Take an appropriate amount of potassium chromate solution, put it in a purifier, and take the agent of lead acetate, and slowly pour it in. In the solution, the color changes and sediment emerges. The color of the sediment is dazzling, like a stroke of God.

The warlock looked at this change and thought deeply about the reason. Potassium chromate meets lead acetate, and the ionic phase is easy to synthesize into a new substance. This new substance is insoluble in water, so it sinks out.

From this perspective, the beauty of chemistry lies in the combination of materials, which can become gratuitous and can cause strange images. If people understand the reason and use it well, it will be beneficial to all things.
