A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7. The neutralization of a strong acid and weak base will have a pH of less than 7, and conversely, the resulting pH when a strong base neutralizes a weak acid will be greater than 7.
Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids. Because not all aqueous reactions form precipitates, one must consult the solubility rules before determining the state of the products and writing a net ionic equation. The ability to predict these reactions allows scientists to determine which ions are present in a solution, and allows industries to form chemicals by extracting components from these reactions.
According to these two definitions, then the 3 reactions on the left are neutralization reactions, and the 3 on the right of the picture are precipitation reactions.

Acids are proton (H+) donors. Bases are proton (H+) acceptors. Acid-base reactions are often "reversible", meaning that they can occur in both a left-to-right and a right-to-left direction. As a result, there is one acid and one base on each side of an acid-base reaction. 1. Identify the Acids and Bases on both sides of the following reactions: a. NH4+ + OH- ⟷ NH3 + H2O b. HCl + H2O ⟷ Cl- + H3O+ c. H2PO4- + H2O ⟷ HPO42- ...
