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
