Net Ionic Equations and Solubility

This video tutorial explains how to write a balanced net ionic equation for the reaction between barium chloride and potassium chromate. It covers balancing the molecular equation, determining the states of substances using solubility rules, and splitting strong electrolytes into ions for the complete ionic equation. The tutorial also discusses identifying and removing spectator ions to arrive at the net ionic equation, emphasizing the importance of charge conservation and the insolubility of barium chromate.
