Are: Ba(NO3)2, Ti)2, MgI2, and Ca(CH3COO)2 soluble or insoluble in H2O @ 25degrees C?
Here is a site that lists the solubility rules. You should know this table; eventually you will want to know it so well that it is memorized. If you still have questions after viewing this table, please repost. I hope this helps. http://www.chem.vt.edu/RVGS/ACT/notes/solubility_rules.html
Barium nitrate, calcium acetate are both soluble. Magnisium iodide is soluble.
thank you! :)
