Net Ionic Equations and Spectator Ions

The video tutorial explains how to write a balanced net ionic equation for the reaction between lithium carbonate (Li2CO3) and sulfuric acid (H2SO4). It begins with balancing the molecular equation, determining the states of each substance, and discussing the solubility of compounds. 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. Finally, the video ensures that both charge and atom counts are balanced in the final equation.
