Net Ionic Equations and Compounds

This video tutorial explains how to write a balanced net ionic equation for the reaction between calcium carbonate and sulfuric acid. It begins with balancing the molecular equation and determining the states of substances using solubility rules. 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 key points about handling insoluble compounds in net ionic equations.
