Document Summary

Chem 101: molecular, total, and net ionic equations and determining the main. The molecular ionic equation will be the balanced chemical equation of a reaction with the correct reduced coefficients. Here is an example of a total ionic equation: If the molecular equation was: naoh (aq) + hcl (aq) h2o (l) + nacl (aq) Na+ (aq) + oh- (aq) + h+ (aq) + cl- (aq) h2o (l) + na+ (aq) + cl- (aq) Only compounds that are originally in the aqueous state and those that are in the aqueous state after the reaction need to be changed into their respective element ion compositions. As you can see here, water is in a liquid state, so we do not need to break it down. To get our net ionic equation, we use our total ionic equation and ignore everything that did not change states in the reaction.
