Net Ionic Equations and Solubility

The video tutorial explains how to write a balanced net ionic equation for the reaction between calcium nitrate and ammonium sulfate. It begins by balancing the molecular equation and then discusses the solubility rules to determine the states of the compounds involved. The tutorial proceeds to split the strong electrolytes into ions to form the complete ionic equation. Spectator ions are identified and removed to derive the net ionic equation, ensuring both atoms and charges are balanced.

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

• Determine the solubility of the compounds

• Write the complete ionic equation

• Balance the molecular equation

• Identify the spectator ions

According to solubility rules, which ions generally form soluble compounds?

• Calcium ions

• Sulfate ions

• Carbonate ions

• Nitrate ions

What is the solubility status of calcium sulfate in water?

• Highly soluble

• Insoluble

• Slightly soluble

• Completely insoluble

What happens to slightly soluble compounds in net ionic equations?

• They are considered soluble

• They are treated as gases

• They are considered insoluble

• They are ignored

What is the purpose of splitting strong electrolytes into ions?

• To identify spectator ions

• To balance the molecular equation

• To form the complete ionic equation

• To determine solubility

What are spectator ions?

• Ions that do not participate in the reaction

• Ions that form a precipitate

• Ions that are insoluble

• Ions that change charge

How do you determine the net ionic equation from the complete ionic equation?

• By adding more ions

• By balancing the charges

• By removing spectator ions

• By changing the coefficients

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

• Depends on the reaction

• Positive

• Negative

• Zero

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

• To comply with the law of conservation of charge

• To satisfy the solubility rules

• To ensure the reaction is spontaneous

• To maintain the law of conservation of mass
