Write net ionic equations for the reactions listed in Problem 4.72.

Key Concepts

Net Ionic Equations

Net ionic equations represent the actual chemical species that participate in a reaction, excluding spectator ions that do not change during the reaction. They are derived from complete ionic equations by removing ions that appear on both sides. This simplification helps to focus on the essential chemical changes occurring in the reaction.

Spectator Ions

Spectator ions are ions that exist in the same form on both the reactant and product sides of a chemical equation. They do not participate in the actual chemical reaction and can be eliminated when writing net ionic equations. Identifying spectator ions is crucial for accurately representing the core chemical processes involved.

Balancing Chemical Equations

Balancing chemical equations is the process of ensuring that the number of atoms for each element is the same on both sides of the equation. This is essential for obeying the law of conservation of mass. A balanced equation provides a clear representation of the reactants and products, which is necessary for deriving the net ionic equation.
