The video tutorial explains how to balance a net ionic equation for the reaction between strontium hydroxide and hydrobromic acid. It begins with balancing the molecular equation, assigning states to each substance, and then splitting strong electrolytes into ions to form the complete ionic equation. Spectator ions are identified and removed to derive the net ionic equation. The tutorial concludes by ensuring the equation is balanced in terms of charge and atoms.
