The video tutorial explains how to write a balanced net ionic equation for the reaction between chloric acid (HClO3) and barium hydroxide (Ba(OH)2). It begins with balancing the molecular equation, assigning states to each substance, and dissociating strong acids and bases. The complete ionic equation is formed, and spectator ions are identified and removed. The final net ionic equation is simplified, ensuring that charges and atoms are balanced.
