Net Ionic Equations and Precipitation

The video tutorial explains how to write a balanced net ionic equation for the reaction between aluminum nitrate and potassium hydroxide. It begins with balancing the molecular equation, then discusses the solubility of compounds and the formation of a precipitate. The tutorial proceeds to split strong electrolytes into ions to form the complete ionic equation, identifies spectator ions, and derives the net ionic equation. Finally, it ensures that the charges are balanced in the net ionic equation, concluding with a review of the process.
