Article Grading: The following comments were left by the quality and importance raters: (edit ยท refresh) It states that a precipitate is the result of a reaction, and is indicative of chemical change having taken place. However precipitates can be formed via alternate routes as well, such as dissolution in hot liquid followed by cooling. |

This isn't very good, and reads like it has been written by a grade schooler. (anon user)

[edit] Why chemical reaction
From your link for definition
Precipitate or the deposit is an insoluble solid formed by reactions in a solution.
Precipitation is also the deposit as result of changing solubility of soluble elements in solid solvent. So chemical reaction is not neccessay. For example carbon can precipitate in steel as pure graphite (theoretically).
[edit] Where Does this come from
"After evaporation, condensation occurs and will slowly turn into a cloud." - This is at the end of the main part of the article and it doesn't make any sense to me. I suggest a deletion. Abcjared 06:27, 23 September 2007 (UTC)
