Net Ionic Equations and Solubility Rules

This video tutorial explains how to balance net ionic equations, starting with balancing the molecular equation. It covers writing the states of substances using solubility rules, splitting strong electrolytes into ions for the complete ionic equation, and identifying spectator ions to derive the net ionic equation. The tutorial concludes with ensuring charge conservation and balancing atoms in the final equation.
