***Explanation
These are metathesis or double displacement reactions. So the cation of the first compound combines with the anion of the second compound to form one product. Then the cation of the second compound combines with the anion of the first compound to form the second product.
Look at the solubility guidelines in Table 4.1 to determine which products are insoluble (and therefore a solid) and which are soluble (and therefore will break apart into ions.)
Then all soluble ionic compounds will break apart into their constituent ions in the Ionic Equation. The insoluble ionic compounds will remain together as a molecule.
If an ion appears on both sides of the equation, then it is a spectator ion. You will cancel the spectator ions out to achieve the NET IONIC equation. This only contains the ions and compounds that are involved in the reaction.
