Mg3(PO4)2 (aq) Cu(NO3)2 (aq) ----> ??? predict product

Question

Mg3(PO4)2 (aq) Cu(NO3)2 (aq) ----> ??? predict product

Answer 1

Mg3(PO4)2 + 3 Cu(NO3)2 >> Cu3(PO4)2 (s)+ 3 Mg(NO3)2(aq)

net ionic :

2 PO43- (aq) + 3 Cu2+ (aq) >> Cu3(PO4)2 (s)

Answer 2

Magnesium salts tend to be more soluable than Copper salts. Nitrates are more soluable on average than phosphates. Therefore, it is reasonable to predict the products will be insoluable Copper phosphate in a solution of magnesium nitrate:

Mg3(PO4)2 + 3Cu(NO3)2 -> 3Mg(NO3)2 + Cu3(PO4)2
