The [... equation] shows all of the ions present in a reaction including spectator ions

complete ionic equation

The [... equation] is a chemical equation for a reaction which lists only those species participating in the reaction

net ionic equation

• does not include spectator ions

[...], also known as [...], is a REDOX reaction where a molecule is transformed into two or more dissimilar products

disproportionation also known as dismutation

A/an [... titration] is similar in methodology to acid-base titrations, however, these titrations follow transfer of charge

redox titration
