Reaction of copper bromide with lead acetate
In the past, chemists studied the reaction of copper (II) bromide (Copper II Bromide) with lead (II) acetate (Lead II Acetate).

Copper (II) bromide, yellow or brown in color, dissolves in water, and the liquid is yellow-green. Lead (II) acetate, often white crystals, is also soluble in water.

When the solutions of the two are mixed, a wonderful change occurs. In an instant, there seems to be something in the solution, and it gradually precipitates. The color of this precipitation is not white or gray, but has a unique appearance, just like the appearance of lead compounds.

The reason is due to chemical reasons. The bromine ion in copper (ⅱ) bromide meets the lead ion in lead (ⅱ) acetate, and the two combine to form an insoluble salt according to the laws of chemistry. The bromide of lead has little solubility in water, so it precipitates from the solution and is precipitated.

Looking at this reaction, it can be seen that chemical substances meet, and according to their characteristics, new things can be born. This is the wonder of chemistry, just like the creation of a craftsman. Although it is invisible, it can turn the ordinary into a miracle and make this unique scene.
