Net Ionic Equations and Spectator Ions

This video tutorial explains how to write a balanced net ionic equation for the reaction between zinc sulfate and sodium carbonate. It covers balancing the molecular equation, determining the solubility and states of compounds, and splitting strong electrolytes into ions to form the complete ionic equation. The tutorial also identifies spectator ions and demonstrates how to write the net ionic equation, ensuring both atoms and charges are balanced.

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

• Determine the solubility of compounds

• Write the complete ionic equation

• Balance the molecular equation

• Identify spectator ions

Which of the following compounds is generally soluble?

• Sodium sulfate

• Lead sulfate

• Zinc carbonate

• Calcium carbonate

What happens to sodium carbonate when it dissolves in water?

• It forms a precipitate

• It reacts with water to form a new compound

• It dissociates into sodium and carbonate ions

• It remains undissolved

In the complete ionic equation, what is the charge of the zinc ion?

• 1-

• 2+

• 1+

• 2-

Why don't we split solids in net ionic equations?

• They are spectator ions

• They are always insoluble

• They do not dissociate into ions

• They are not involved in the reaction

What is a spectator ion?

• An ion that changes its charge during the reaction

• An ion that forms a precipitate

• An ion that is present in the same form on both sides of the equation

• An ion that participates in the reaction

Which ions are removed to derive the net ionic equation?

• Spectator ions

• Ions that are not involved in the reaction

• Ions that form a precipitate

• Ions that change their oxidation state

What is the net charge on both sides of a balanced net ionic equation?

• Negative

• Varies depending on the reaction

• Positive

• Zero

What is the final product of the reaction between zinc sulfate and sodium carbonate?

• Zinc carbonate

• Sodium sulfate

• Sodium carbonate

• Zinc sulfate

Why is it important to balance both atoms and charges in a net ionic equation?

• To make the equation easier to read

• To identify spectator ions

• To comply with the law of conservation of mass and charge

• To ensure the reaction is spontaneous
