Net Ionic Equations and Spectator Ions

The video tutorial explains how to write a balanced net ionic equation for the reaction between copper(II) hydroxide and sulfuric acid. It begins by balancing the molecular equation and identifying the states of each substance 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. Finally, the video ensures that both atoms and charge are balanced in the final equation.

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

• Split strong electrolytes into ions
