Module 4.3: Net Ionic Equations

GOAL(s):

• Predict whether or not a precipitation reaction will occur.
• Write net ionic equations for reactions in aqueous solutions.

DEFINITIONS:

spectator ion: an ion that is present in a solution in which a reaction takes place, but is not changed during the reaction process.

net ionic equation: a chemical equation in which only those ions undergoing chemical changes during the course of the reaction are represented.
