This video tutorial explains how to write the net ionic equation for the reaction between sulfuric acid (H2SO4) and lithium hydroxide (LiOH). It covers the steps of balancing the molecular equation, determining the states of substances, splitting strong electrolytes into ions, and forming the complete ionic equation. The tutorial also demonstrates how to identify and remove spectator ions to derive the net ionic equation, and concludes with simplifying the equation by reducing coefficients.
