"The Reaction of Lead Acetate and Potassium Iodide"

In the past year, there have been scholars in the study to study the reaction of various drugs. One day, take lead acetate and potassium iodide, want to see the sympathetic change between the two.

It is placed in a dish of lead acetate, its color is crystal clear, like thin ice, shining and shining. The solution of potassium iodide is slowly poured into the solution, and the liquid is clear, like the dew of autumn morning. In an instant, the two touch, and a strange image emerges. In the solution, the gradual condensation of yellow precipitation, if the yellow cloud descends on the abyss pool, slowly settle. Its quality is delicate, like a golden millet, bright color, eye-catching.

The scholar gazed at this scene and thought to himself: The combination of the two will produce new matter. Then he recorded the situation in detail and repeated the investigation. Thinking about the principle of this reaction, or due to the agreement of ions and the reorganization of the structure, this change of precipitation can be caused. Therefore, the scholar has a deep understanding of the wonder of the sympathetic nature of matter, and has added new knowledge to the principle of chemistry. Later scholars, if they study the reaction of the two, they should take this as a reference, investigate its changes carefully, and explore the infinite secrets of chemistry.
