Ammonia solution preparation
Thread Content
Why do flocs form when preparing ammonia solution using tap water? A chemical reaction must have taken place.
Perhaps the hardness of the tap water is high, with a high content of calcium and magnesium ions; these ions react with the OH- ions produced by the hydrolysis of ammonia to form white precipitates of calcium hydroxide and magnesium hydroxide.
It makes sense; we think the same. Thank you.
It is recommended to check out a book on inorganic chemistry. The precipitates are calcium carbonate and magnesium hydroxide. Deionized water must be used to prepare ammonia solution
