Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Complete Ionic Equation
A complete ionic equation represents all the ions present in a solution during a chemical reaction. It shows the reactants and products in their ionic forms, highlighting the dissociation of soluble ionic compounds in aqueous solutions. This equation is essential for understanding how ions interact in solution and sets the stage for identifying the net ionic equation.

Complete Ionic Equations
Net Ionic Equation
The net ionic equation simplifies the complete ionic equation by removing spectator ions—ions that do not participate in the actual chemical reaction. This equation focuses solely on the species that undergo a change, providing a clearer picture of the chemical process. It is particularly useful for emphasizing the essential components of a reaction and understanding the underlying chemistry.

Acid-Base Neutralization Reaction
An acid-base neutralization reaction occurs when an acid reacts with a base to produce water and a salt. In the given reaction, hydrochloric acid (HCl) reacts with lithium hydroxide (LiOH), resulting in the formation of water (H2O) and lithium chloride (LiCl). Understanding this type of reaction is crucial for predicting the products and writing the corresponding ionic equations.
