Precipitation Reactions
Definition of precipitation –



Definition of Double-Displacement Reaction w/ basic equation –



Three steps to solve for a precipitate.
    1. Note the ions present in the reactants.

    2.   Consider the possible cation-anion combo.

    3.   Predict whether any of the combinations are insoluble.
Predicting Precipitation
Example            Sodium sulfate (aq) + strontium nitrate (aq)
#1        (Na+) (SO42-)             +       (Sr2+) (NO3-)              


          Na2SO4                    +         Sr(NO3)2                 


#2        A B                       +          C D                           A D        +   C B


          Na2SO4                    +         Sr(NO3)2                      2NaNO3      +   SrSO4


#3        NaNO3 all nitrates are soluble                                     SOLUBLE
