Double Replacement Rxn - Neutralization Rxn

ChemistryWiki | RecentChanges | Preferences

As you know, one of three products (form a solid, water or gas) must be produced in a double chemical reaction for the reaction to occur. Here, we will explain formation of one of these products: the formation of water.

As with all double replacement reactions, you have two reactants that are aqueous (compounds that break-up into their ions in water). In other words, you have a bucket of ions before the reaction occurs. The task is to rearrange the ions into new compounds (cpds) knowing that like charged ions can't create cpds.

Even though water (H2O) is a molecular cpd, we often think of it as made up of two ions, hydronium ion (H+1) and hydroxide ion (OH-1). It would look like HOH if written as a cpd. Therefore, one of our reactants must contain the hydroxide ion (OH-1) and one must contain the hydronium ion (H+1). If you place these two reactants into a bucket, you product water (H2O). See example below.

These types of reactions are very common place to the point that we give the reactants and chemical reaction special names:

Net Ionic Reaction for Neutralization Reactions

To determine any Net Ionic Reaction, you must follow the directions stated in (NetIonicReactions).

(The Special Condition for Net Ionic Reactions of Neutralization is that all neutralization reactions have the same Net Ionic Reaction: the one above)
