Net Ionic Equations and Electrolytes

This video tutorial explains how to write a balanced net ionic equation for the reaction between ammonia (NH3) and acetic acid (CH3COOH). It covers balancing the molecular equation, assigning states to substances, and identifying strong and weak electrolytes. The tutorial emphasizes that NH3 and CH3COOH are weak electrolytes and should not be split into ions, while ammonium acetate is a strong electrolyte and should be split. The video concludes with a net ionic equation where no spectator ions are present, ensuring charge and atom balance.

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

• Identify spectator ions

• Balance the molecular equation

• Write the complete ionic equation

• NH4+ and CH3COO-

What are spectator ions?

• Ions that are only on the product side

• Ions that are only on the reactant side

• Ions that form a precipitate

• Ions that do not participate in the reaction

What is the key to writing the net ionic equation for ammonia and acetic acid?

• Recognizing acetic acid as a strong acid
