The video tutorial explains how to balance the net ionic equation for hypochlorous acid and calcium hydroxide. It begins with balancing the molecular equation, treating the hypochlorite ion as a single entity. The tutorial then assigns states to each substance, noting that hypochlorous acid is a weak acid and calcium hydroxide is a strong base. The complete ionic equation is formed by splitting strong electrolytes into ions, while weak acids and liquids remain intact. Spectator ions are removed to derive the net ionic equation, ensuring charge and atom balance. The tutorial concludes with a review of the balanced net ionic equation.
