Net Ionic Equations and Spectator Ions

The video tutorial explains how to write a balanced net ionic equation for the reaction between nickel and lead(II) nitrate. It begins with balancing the molecular equation, then assigns states to each substance. The tutorial proceeds to split strong electrolytes into ions for the complete ionic equation, identifies and removes spectator ions, and concludes with the net ionic equation, ensuring charge and atom balance.

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

• Write the states of substances

• Balance the molecular equation

• Identify spectator ions

• Split strong electrolytes into ions

Which of the following is a solid in the reaction between nickel and lead(II) nitrate?

• Nickel

• Lead(II) nitrate

• Nitrate ions

• Water

What is the state of nitrates in the reaction?

• Solid

• Liquid

• Gas

• Aqueous

What is the purpose of splitting strong electrolytes into ions?

• To identify spectator ions

• To determine the reaction rate

• To find the limiting reactant

• To balance the equation

Which ions are considered spectator ions in this reaction?

• Nickel ions

• Lead ions

• Hydrogen ions

• Nitrate ions

What must be conserved in a balanced net ionic equation?

• Mass only

• Charge only

• Neither mass nor charge

• Both mass and charge

What is the charge on nickel in the net ionic equation?

• 0

• 1+

• 2+

• 3+

Why is it important to remove spectator ions from the equation?

• They do not participate in the reaction

• They change the reaction rate

• They alter the product formation

• They affect the temperature of the reaction
