Precipitate?

Na3PO4 + BaCl2 Ba+2 PO4-3 + Na+1 Cl-1

Barium phosphate is

not soluble so a precipitate

forms

Ba3(PO4)2 (s) + NaCl(aq)

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.

Example

AgNO3 + NaCl AgCl + NaNO3

1. First, we separate the compounds into ions:

Ag1+ + NO31- + Na1+ + Cl1-

2. Next we “switch” the cations3. Last we determine if a precipitate will

form using the solubility chartAgCl + Na1+ + NO3

1-

Note that the AgCl did not ionize, because it is a “precipitate”
