Net Ionic Equations and Solubility

This video tutorial guides viewers through balancing a net ionic equation for potassium carbonate and copper(II) nitrate. It begins with balancing the molecular equation, followed by determining the solubility and states of the compounds involved. 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 discussion on charge conservation and the final balanced equation.
