Module 4.3: Net Ionic Equations

Step 2: Use the general guidelines of solubility for ionic compounds to determine solubilities of reactants and products.

Is Pb(NO3)2 soluble in water?	Yes		No		Click on buttons to review solubility rules.
Is HCl soluble in water?	Yes		No
Is PbCl2 soluble in water?	Yes		No
Is HNO3 soluble in water?	Yes		No

Step 3: Recognize that all soluble ionic compounds dissociate into their component ions in aqueous solution.

Under the equation below, select the correct ions that will be in solution when each soluble compound dissociates.

Pb2+	2 H+		2 H+
Pb+	H22+		H22+
(NO3)22-	2 Cl-		(NO3)22-
2 NO3-	Cl22-		2 NO3-

Step 4: Write a complete ionic equation with the ions in solution from each soluble compound shown separately.

Using the ions you selected above, you can write the complete ionic equation as follows:

Step 5: Cancel out the spectator ions from each side of the complete ionic equation to create the net ionic equation.

Click on the spectator ions in the equation below.

Step 6: Check to see that the sum of the charges is the same on each side of the net ionic equation.

Fill in the sum of the charges of the reactants and products below.
