What Is Acid Precipitation?
In chemical changes, there are generally eight major precipitates. Silver chloride and barium sulfate are insoluble in acid, and the other six precipitates are soluble in acid.

- In chemical changes, there are generally eight major precipitates. for
- AgCl (silver chloride) BaSO4 (barium sulfate) CaCO3 (calcium carbonate) BaCO3 (barium carbonate) Al (OH) 3 (aluminum hydroxide)
- Mg (OH) 2 (magnesium hydroxide) Cu (OH) 2 (copper hydroxide) Fe (OH) 3 (iron hydroxide)
- Among them, AgCl, BaSO4, CaCO3, BaCO3, Al (OH) 3 and Mg (OH) 2 are white precipitates, Cu (OH) 2 is blue flocculent precipitate, and Fe (OH) 3 is red-brown precipitate. Silver chloride and barium sulfate are insoluble in acid, calcium carbonate and barium carbonate are soluble in acid with bubbles, and magnesium hydroxide, aluminum hydroxide, iron hydroxide and copper hydroxide are soluble in acid without bubbles. Precipitation usually occurs in a metathesis reaction, where copper hydroxide is usually formed by the reaction of copper sulfate and sodium hydroxide.
