Net Ionic Equations and Spectator Ions

The video tutorial explains how to balance the net ionic equation for cesium hydroxide and sulfuric acid. It begins with balancing the molecular equation, assigning states to each substance, and splitting strong electrolytes into ions. Spectator ions are identified and crossed out to derive the net ionic equation. The tutorial concludes by ensuring the equation is balanced in terms of charge and atoms.

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