Net Ionic Equations and Reactions

The video tutorial explains how to write a balanced net ionic equation for the reaction between hydrochloric acid and ammonium carbonate. It begins with balancing the molecular equation, assigning states to each substance, and then forming the complete ionic equation. Spectator ions are identified and removed to derive the net ionic equation. The tutorial emphasizes the importance of balancing atoms and charges, and notes the decomposition of carbonic acid into carbon dioxide and water.

What is the first step in writing a balanced net ionic equation?

• Identify spectator ions

• Balance the molecular equation

• Write the states for each substance

• Split strong electrolytes into ions

Why is hydrochloric acid considered a strong acid in the context of net ionic equations?
