Net Ionic

What are the different ways to write equations for ionic reactions in water?

• Ionic compounds disassociate in water

Ex: Sodium Chloride and water

Demo

• Lead (II) Nitrate and Sodium Iodide solutions(made by dissolving ionic compounds in water)

Pb(NO3)2 (aq) + NaI (aq) PbI2(s) + NaNO3(aq)

• Break it down into its ions to give a complete net ionic equation

• What is a spectator ion? (cross these out, they don’t actually “play” in the game)

• What is left?
