This video tutorial explains how to write a balanced net ionic equation for the reaction between calcium nitrate and potassium hydroxide. It begins by balancing the molecular equation, then determining the states of each substance using solubility rules. The tutorial proceeds to split strong electrolytes into ions to form the complete ionic equation. Spectator ions are identified and crossed out to derive the net ionic equation. The video concludes with a summary of the balanced net ionic equation, emphasizing the importance of charge and atom balance.
