Here are the essential concepts you must grasp in order to answer the question correctly.
Net Ionic Equations
A net ionic equation represents the chemical species that are involved in a reaction, excluding spectator ions that do not participate in the actual chemical change. It focuses on the ions and molecules that undergo a transformation, providing a clearer picture of the reaction's essence. To write a net ionic equation, one must first identify the reactants, their states, and the products formed.

Solubility Rules
Solubility rules are guidelines that help predict whether a compound will dissolve in water. They indicate which ionic compounds are soluble or insoluble in aqueous solutions. Understanding these rules is crucial for determining if a reaction will occur when two solutions are mixed, as insoluble products may precipitate out of solution, leading to a net ionic equation.

Precipitation Reactions
Precipitation reactions occur when two soluble salts react in solution to form an insoluble salt, which precipitates out of the solution. This type of reaction is common in double displacement reactions, where the cations and anions exchange partners. Recognizing whether a precipitate forms is essential for writing the net ionic equation and understanding the overall reaction process.
