 for Precipitate?
Na3PO4 + BaCl2  Ba+2 PO Na+1 Cl-1
Barium phosphate is not soluble so a precipitate forms
Ba3(PO4)2 (s) NaCl(aq)

29. Precipitates in Double Replacement Reactions
Many DR reactions occur in water- that is, in aqueous solution
When dissolved in water, many ionic compounds “dissociate”, or separate, into cations and anions
If the rearrangement of the ions forms a solid it is called a precipitate.
A precipitate is a solid produced during a chemical reaction in a solution.

30. Example AgNO3 + NaCl  AgCl + NaNO3
1. First, we separate the compounds into ions:
Ag1+ + NO31- + Na1+ + Cl1- 
2. Next we “switch” the cations
3. Last we determine if a precipitate will form using the solubility chart
AgCl + Na1+ + NO31-
Note that the AgCl did not ionize, because it is a “precipitate”
