Molecular, Complete Ionic & Net Ionic Equations

Writing Chemical Reactions is based on our understanding of the Solubility Rules

The Chemical Reaction

When writing a chemical reaction our reactants break up into ions and then reassemble to create products. This type of reaction is referred to as a double displacement or metathesis

Writing Chemical Reactions

A balanced molecular equation is an equation showing the neutral forms of compounds. 

All that happens is that soluble ionic compounds separate and become ions in the chemical equationl. This represents the total or full ionic equation

In a balanced molecular equation reactant compounds exist as ions that recombine to form products. 

In a total ionic equation only the compounds that are aqueous can break up into ions. 

In a net ionic equation the spectator ions are removed and what remains is the net ionic equation

Remember when asked to write a complete and balanced molecular equation that a reaction only occurs if a solid, liquid or gas is formed as a product. 

Problem: Predict whether a reaction occurs, and write the balanced total and net ionic equations.

If your chemical equation produces only aqueous products then the answer is NO REACTION.
