Ionic Reactions and Equations

The video tutorial explains how to write a balanced net ionic equation for the reaction between barium hydroxide and sodium sulfate. It begins with balancing the molecular equation by adjusting coefficients, then identifies the states of each substance, noting that barium sulfate is insoluble. The tutorial proceeds to form the complete ionic equation by splitting strong electrolytes into ions. Spectator ions are identified and removed, leaving the net ionic equation. The tutorial concludes by verifying that both atoms and charges are balanced in the final equation.
