Net Ionic Equations and Spectator Ions

The video tutorial explains how to write a balanced net ionic equation for the reaction between lead(II) nitrate and iron(III) chloride. It begins with balancing the molecular equation, followed by determining the solubility of compounds to assign states. 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 discussion on reducing coefficients for a neater presentation.

What is the first step in writing a net ionic equation?
