Check the solubility constant of the salt to be formed.

This, however, is only a question on my textbook and no specimen results is given. [quote]原帖由 [i]jmlo[/i] 於 2013-8-19 10:40 PM 發表 [url=http://www.discuss.com.hk/redirect.php?goto=findpost&pid=369801383&ptid=22330675][img]http://www.discuss.com.hk/images/common/back.gif[/img][/url]

Without knowing which cations and anions are involved, you can't predict if the salt will form precipitate.
