EXAMPLE 3 Predicting Precipitation Reactions:  Predict whether a precipitate will form when lead(II) nitrate, Pb(NO3)2(aq), and sodium acetate, NaC2H3O2(aq), are mixed.  If there is a precipitation reaction, write the complete and net ionic equations that describe the reaction.

### Solution:

Step 1:  Determine the possible products using the general double displacement equation.

AB  +  CD        AD  +  CB

The possible products from the mixture of Pb(NO3)2(aq) and NaC2H3O2(aq) are Pb(C2H3O2)2 and NaNO3.

Pb(NO3)2(aq) + NaC2H3O2(aq)  to Pb(C2H3O2)2 and NaNO3

Step 2:    Predict whether either of the possible products is water insoluble.

According to our solubility guidelines, compounds with nitrates and acetates are soluble, so both Pb(C2H3O2)2 and NaNO3 are soluble.

### There is no precipitation reaction.
