=//**Double Displacement**//=

Double displacement is when an cation and anion of two different molecules swap places to form two new compounds. This is represented by AB+CD--->AD+CB

An example of a double displacement reaction is when lead(II) nitrate reacts with potassium iodide to produce lead(II) iodide and potassium nitrate. To create the formula, you wirte the symbols for the elements or compounds, ind the charges, and do the "switcheroo" to find the amount of each. The formula for this would be: Pb(NO3)2 + KI ---> PbI2 + KNO3

This is the balanced equation: Pb(NO3)2 + 2KI ---> PbI2 + 2KNO3 Because there are 2 potassiums on the left side of the equation, you have to add the coefficient 2 on the right side to make them equal.
