In "Tiangong Kaiwu", lead dan ($Pb_3O_4 $), also known as red pill and yellow pill. Its properties are unique and have many physical and chemical properties.
From the perspective of physical properties, lead dan is orange-red crystals or powder, with bright and eye-catching color. It was often used as a pigment in ancient times for painting, ceramics and other processes to add color to utensils. And its texture is delicate, the touch is unique, and it is well mixed with many substances, which is convenient for processing and application in different fields.
In terms of chemical properties, lead dan is oxidizing. If it encounters a reducing agent, a redox reaction will occur. Under certain conditions, it can react with reducing agents such as carbon and carbon monoxide and be reduced to lead elemental matter. This property is of great significance in the fields of metallurgy and chemical synthesis. In addition, lead dan can react with acid. Taking nitric acid as an example, lead dan reacts with nitric acid to generate lead nitrate, water and oxygen. This reaction provides ideas and methods for the determination of lead dan content in analytical chemistry.
It should be noted that lead dan contains lead elements and is toxic. Although it has important uses in specific processes and chemical reactions, improper use can cause harm to human health and the environment. When the ancients used lead dan, they gradually realized its toxicity, so corresponding protective measures were also taken in actual operation to avoid its harm.
