Net Ionic Equations and Solubility

The video tutorial explains how to write and balance net ionic equations, using sodium hydroxide and barium nitrate as examples. It begins with balancing the molecular equation, followed by discussing the solubility of compounds and their ionic states. The tutorial then covers the complete ionic equation, highlighting spectator ions and the concept of no reaction. The video concludes with an explanation of why barium hydroxide is considered soluble in this context.

What is the first step in writing a balanced net ionic equation?

• Write the complete ionic equation

• Determine solubility of compounds
