Net Ionic Equations and Solubility

This video tutorial explains how to write a balanced net ionic equation for the reaction between barium nitrate and nickel sulfate. It begins with balancing the molecular equation and identifying the states of each substance using solubility rules. The tutorial then demonstrates how to split strong electrolytes into ions to form the complete ionic equation. Spectator ions are identified and removed to derive the net ionic equation. The video concludes by ensuring charge conservation and atom balance in the final equation.
