Net Ionic Equations and Spectator Ions

The video tutorial explains how to balance a net ionic equation for aluminum and lead(II) nitrate. It begins with balancing the molecular equation, then writing the states of each substance. The tutorial covers splitting strong electrolytes into ions to form the complete ionic equation and identifying spectator ions to derive the net ionic equation. Finally, it ensures the net ionic equation is balanced in terms of atoms and charge.

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

• Split strong electrolytes into ions

• Write the states of substances

• Balance the molecular equation

• Identify spectator ions

Which of the following is a characteristic of nitrates in a solution?

• They are very soluble

• They are gases

• They are insoluble

What do you do after writing the states for each substance?

• Balance the charges

• Split strong electrolytes into ions

• Identify the products

• Cross out spectator ions

What is the purpose of identifying spectator ions?

• To determine solubility

• To simplify the equation

• To identify reactants

• To balance the equation

Which ions are considered spectator ions in this reaction?

• Lead ions

• Hydrogen ions

• Aluminum ions

• Nitrate ions

What is the result after removing spectator ions from the complete ionic equation?

• The solubility rules

• The unbalanced ionic equation

• The net ionic equation

• The balanced molecular equation

What must be checked to ensure the net ionic equation is correct?

• The balance of atoms and charge

• The presence of gases
