(b) Aqueous barium hydroxide is neutralized by aqueous nitric acid.

Key Concepts

Neutralization Reaction

A neutralization reaction is a type of chemical reaction in which an acid and a base react to form water and a salt. This reaction is fundamental in understanding acid-base chemistry and is characterized by the combination of H? ions from the acid and OH? ions from the base to generate water.

Ionic Equations

Ionic equations are representations of chemical reactions that show all of the ions present in the reaction. They are particularly useful in aqueous reactions involving strong electrolytes because these substances are completely dissociated into ions in solution.

Net Ionic Equations

Net ionic equations focus on the species that actually participate in the chemical reaction. By omitting spectator ions – ions that remain unchanged on both the reactant and product side – these equations simplify the reaction to its core chemical process, making it easier to understand the underlying mechanism.

Spectator Ions

Spectator ions are ions present in solution that do not participate in the actual chemical change during a reaction. They appear unchanged on both sides of the ionic equation and are therefore omitted in the net ionic equation to highlight the essential reactive species.

Complete Dissociation

Complete dissociation refers to the process by which strong acids and strong bases separate entirely into their constituent ions in aqueous solution. This concept is critical when writing ionic equations because it justifies representing these compounds as free ions, which aids in understanding the ionic nature of the reaction.
