Make it Rain
One common reaction is a precipitation reaction.
Mixing together two aqueous solutions of ionic compounds will cause a double replacement reaction. If one of the products formed is insoluble then it will separate out of the solution.

Not every ionic compound is soluble in water. Below are general rules for determining if an ionic compound is soluble.

Molecular Equations, Ionic EquaTIONS AND Net Ionic Equations
The reaction above is known as a balanced molecular equation. It shows the formulas of the ionic compounds.
But the ions of the reactants are dissolved in water and do not exist as formula units, but separate ions. The equation below is closer to reality and shows the dissolved ions. We refer to this equation as the ionic equation.
Notice that the Li+ and NO3- ions remain the same on both sides of the reaction. They do not actively participate in the reaction and are therefore classified as spectator ions. Removing the spectator ions yields the net ionic equation.
