Explanation:

Predicting Precipitation Reactions: Predict whether a precipitate will form when water solutions of silver nitrate, AgNO3(AQ), and sodium sulfide, Na2S(AQ), are mixed. If there is a precipitation reaction, write the complete and net ionic equation that describes the reaction.

How does precipitation occur in chemistry?

Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids.
