Q

What is the difference between a complete ionic equation and a net ionic equation?

A

For a complete ionic equation, separate into ions: all (aq) ionic substances; all (aq) strong acids (i.e. HCl, HBr, HI, HNO3, HClO4 and H2SO4, which should be separated into H+ and HSO4–)

Cancel out any ions that appear the same on both sides of the complete ionic equation from in order to obtain the net-ionic equation.
