Identify the states of matter for each compound: NaOH(aq), HC_2H_3O_2(aq), H_2O(l), and NaC_2H_3O_2(aq).
Write the balanced molecular equation: NaOH(aq) + HC_2H_3O_2(aq) → H_2O(l) + NaC_2H_3O_2(aq).
Break down the aqueous compounds into their ions to write the complete ionic equation: Na^+(aq) + OH^-(aq) + HC_2H_3O_2(aq) → H_2O(l) + Na^+(aq) + C_2H_3O_2^-(aq).
Identify the spectator ions, which are ions that appear on both sides of the complete ionic equation without undergoing any change. In this case, Na^+(aq) is the spectator ion.
Write the net ionic equation by removing the spectator ions: OH^-(aq) + HC_2H_3O_2(aq) → H_2O(l) + C_2H_3O_2^-(aq).

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

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 on the species that undergo a change, providing a clearer picture of the chemical process. It is crucial for understanding the essence of the reaction and the formation of products.

Net Ionic Equations

Acid-Base Reaction

An acid-base reaction involves the transfer of protons (H⁺ ions) between reactants, typically resulting in the formation of water and a salt. In the given reaction, sodium hydroxide (a base) reacts with acetic acid (an acid) to produce water and sodium acetate. Understanding this concept is vital for predicting the products and writing the corresponding ionic equations.
