Double+Displacement+P+Grady


 * Definition:** A reaction in which the positive ion of one compound replaces the positive ion of the other compound to produce two new compounds. Basically your two metals switch.


 * Generic Formula:** **AB + CD > CB + AD**

A sentence for this kind of reaction is Potassium Hydroxide and Iron (111) Chloride react to form Iron (111) Hydroxide and Potassium Chloride. The Equation looks like **K(OH) + Fe3 Cl3 -> Fe3(OH)3 + KCl**. To balance this equation you have to add a **3** in front of the **K(OH)** on the left side. Then you have to add a **3** in front of the **KCl** on the right side. The final balanced equation should look like **3K(OH) + Fe(111)Cl3 > Fe3(OH)3 +3KCl**. The two metals that switched were Iron and Potassium.
