4-31 Predict whether a precipitate will form when aqueous solutions of the following compounds are mixed. If a precipitate will form, write its formula and write a net ionic equation for its formation. To make your predictions, use the solubiity generalizations in
Section 4-3.
(a)
Interpretation:
Whether the given reaction gives precipitate or not should be determined. If yes, the formula of the product should be written along with the net ionic equation.
Concept Introduction:
When two aqueous solutions are mixed together, this may or may not result in formation of an insoluble solid in the solution. This insoluble solid is called precipitate and this reaction is called precipitation reaction.
For example, a reaction in which A and C displace each other from their respective solutions. Since two displacement takes place, this reaction is also called double displacement reaction.
