Net Ionic Equations and Electrolytes

The video tutorial explains how to write a balanced net ionic equation for the reaction between potassium carbonate and lead(II) nitrate. It begins with balancing the molecular equation, then discusses the solubility of the compounds involved, identifying which are soluble and which are insoluble. The tutorial proceeds to form the complete ionic equation by splitting strong electrolytes into their ions. Finally, it derives the net ionic equation by removing spectator ions, ensuring charge and atom balance, and concludes with a brief summary of the process.

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

• Balance the molecular equation

• Identify spectator ions

• Determine solubility of compounds

• Split strong electrolytes into ions

What is the role of a coefficient in balancing equations?

• To identify spectator ions

• Potassium carbonate

• Ammonium chloride

• Water

Which ions are considered spectator ions in this reaction?

• Lead ions

• Potassium and nitrate ions

• Carbonate ions

• All ions are spectator ions

What happens to spectator ions in a net ionic equation?

• They are included in the final equation

• They are removed from the equation

• They change their charge

• They form a precipitate

What is the net charge of the balanced net ionic equation?

• 1+

• 2+

• 2-

• 0

Why is it important to ensure charge balance in a net ionic equation?

• To make the equation look nicer

What is the significance of writing the positive ion first in some equations?

• It affects the solubility

• It is a requirement for all equations

• It changes the reaction outcome

• It is a matter of convention and aesthetics
