net ionic equations

[Margaret Akey]

do we know how to write and reduce net ionic equations for the exam?

We probably won't be graded on writing the net ionic equation, but you need the basic understanding that acids and bases and consequential products. The understanding of spectator ions will help you figure what products will be formed and concentrations of [H+] and [OH-].

[Jewelyana3A]

In order to write a net ionic equation you must:
1. Balance the molecular equation.
2. Write the balanced complete ionic equation.
a) break all soluble strong electrolytes (compounds with aqueous beside them) into their ions.
b) bring down all compounds with a s, l, or, g unchanged...
3. Cross out the spectator ions that are present. (Spectator ions are ions that are present in the reaction mixture but do not participate in it. They are usually present on both sides of the equation. They will always have the same exact formula, charge, and physical state. They will also be present in exactly the same number of both sides of the equation.)
4. What isn't crossed out is the net ionic equation.

I'm sure it won't be too complicated on the final. You may just need to have an understanding of what it is and briefly apply it to a problem.
