Net Ionic Equations and Reactions

This video tutorial guides viewers through writing a balanced net ionic equation for the reaction between nickel(II) nitrate and sodium phosphate. It begins with balancing the molecular equation, followed by applying solubility rules to determine the states of substances. The tutorial then explains 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 with a check for charge and atom balance, emphasizing the importance of error checking.
