What is a net ionic equation?
|
a net ionic equation shows only those particles inovlved in the reaction and is balanced with respect to mass and charge
|
|
|
How can you predict the formation of a precipitate?
|
You can predict the formation of a precipitate by using the general rules for solubility of ionic compounds
|

|
|
|
What’s the big deal with solubility?
|
Well, if the ion is soluble, it won’t form a precipitate, and this means it doesn’t react and should be left out of the net ionic equation. The key is first to write the compound’s chemical formula and then determine if it’s soluble. If it is soluble, then ionize it—if it isn’t, don’t ionize it; leave it as a molecule.
