Homework Help: Grade 12 chemistry

Posted by Teneal on Saturday, December 31, 2011 at 6:58pm.

For a chem lab, i was given a table that results when pairs of chemical solutions are mixed.For each set of compounds that formed a precipitate, I had to determine the precipitate. I have done that and now one of the questions i have to answer based on the lab: Based on your results (and only your results), would you expect the following compounds to be soluble or insoluble? The compounds are
1)Li2CrO4
2)Mg(NO3)2
3)CaSO4
4)CuCl2
What i do not know is how to I tell, based solely on my results which of these would be soluable or insoluable. I would appreciate any intel. Thanks
