Net Ionic Equations and Solubility

The video tutorial explains how to write the balanced net ionic equation for the reaction between iron(III) chloride (FeCl3) and ammonium hydroxide (NH4OH). It begins with balancing the molecular equation, followed by determining the solubility and states of the compounds involved. 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 with a verification of charge balance and atom count.
