Net Ionic Equations and Spectator Ions

This video tutorial explains how to write a balanced net ionic equation for the reaction between sodium acetate and sulfuric acid. It begins with balancing the molecular equation, then discusses the states of each substance, focusing on solubility and the nature of acids. The tutorial proceeds to split strong electrolytes into ions to form the complete ionic equation. Spectator ions are identified and removed to derive the net ionic equation. The video concludes by verifying the balance of charges and atoms in the final equation.

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

• Write the complete ionic equation

• Determine the solubility of compounds

• Balance the molecular equation

• Identify spectator ions

Which of the following is a strong acid that dissociates completely in water?

• Sodium acetate

• Water

• Sulfuric acid

• Acetic acid

Why is acetic acid not split into ions in the net ionic equation?

• It is insoluble in water

• It reacts completely with sodium acetate

• It is a weak acid and dissociates very little

• It is a strong acid

What is the purpose of splitting strong electrolytes into ions?

• To identify spectator ions

• To balance the molecular equation

• To determine solubility

• To form the complete ionic equation

What are spectator ions?

• Ions that are weak acids

• Ions that participate in the reaction

• Ions that do not change during the reaction

• Ions that are insoluble

Which ions are considered spectator ions in the reaction between sodium acetate and sulfuric acid?

• Hydrogen ions

• Acetate ions

• Sulfate ions

• Sodium ions

What must be ensured when finalizing the net ionic equation?

• The equation is balanced in terms of mass and charge

• All compounds are split into ions

• All spectator ions are included

• The equation is written in molecular form

What is the net ionic equation for the reaction between sodium acetate and sulfuric acid?

• CH3COOH + H+ → CH3COOH2+

• CH3COOH + H+ + SO4^2- → CH3COOH2+ + SO4^2-

• CH3COOH + H+ → CH3COOH2+

• CH3COOH + Na+ + SO4^2- → CH3COONa + H2SO4

What is the charge balance in a net ionic equation?

• There is no charge balance in net ionic equations

• The total charge on the reactant side is greater than the product side

• The total charge on the reactant side is less than the product side

• The total charge on the reactant side equals the total charge on the product side
