Problems on Net Ionic Equations:
Show the
total ionic and net ionic forms of the following equations. If all species are spectator ions, please
indicate that no reaction takes place.
Note! You need to make sure the
original equation is balanced before proceeding! A set of solubility rules are given at the end of this document.
