What is the formation of a precipitate and what is an example of this phenomenon in everyday life?
gpt
The formation of a precipitate is a sign of a chemical change where a solid forms after two solutions are mixed, such as when magnesium and calcium oxides mix with water in plumbing and form deposits that clog the pipes.
Explanation: Precipitates are evidence of chemical reactions, and the mixing of solutions can result in these insoluble solids, like the minerals that clog pipes over time.
