Synthesis of lead acetate
Lead is also one of the hardware. To obtain lead acetate, there are various methods.

First, mix lead powder with acetic acid. First place an appropriate amount of lead powder in a clean vessel, and slowly inject acetic acid. Acetic acid is mild in nature, and when it meets lead powder, it gradually changes into a combination. In the meantime, there is a slight effervescence of gas, which seems to be boiling but not boiling. When the reaction is stable and the tablet is left standing, the liquid gradually clarifies, and a solution containing lead acetate is obtained. After evaporation, the water is removed, and the crystal of lead acetate can be obtained. When evaporating, the heat should be carefully adjusted. If it is too fierce, the crystal will be damaged, and if it is too slow, it will take a long time.

Second, it is made of lead particles and acetic anhydride. The lead particles are solid and put into a vessel containing acetic anhydride. Acetic anhydride is more active, and it reacts quickly when it comes into contact with lead particles. There is heat transpiration, and the color changes slightly. After the reaction is completed, it should be properly treated, such as filtering and purifying genera, and pure lead acetate can also be obtained. In this process, protection should not be ignored. Acetic anhydride is corrosive and must be avoided.

Or react with lead oxide and acetic acid. When lead oxide encounters acetic acid, the speed of synthesis is also. Looking at the reaction, heat is dissipated, and the color of the solution is gradually changed. After the reaction is completed, lead acetate can also be obtained by separating and purifying it according to the usual method. This way is more convenient, but the choice of raw materials and the matching of proportions are all related to the success or failure of the synthesis.

All these synthetic methods have their own advantages and disadvantages. In order to seek the best results, we should carefully investigate and investigate in practice, depending on the required quantity and quality, carefully select methods, and operate strictly to obtain satisfactory lead acetate.
