Net Ionic Equations and Spectator Ions

The video tutorial explains how to write a balanced net ionic equation for the reaction between silver nitrate and barium bromide. It begins with balancing the molecular equation, followed by determining the solubility and states of the compounds involved. The tutorial then demonstrates how to write the complete ionic equation and identify spectator ions to derive the net ionic equation. Finally, it emphasizes the importance of charge balance and simplification of the equation.

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

• Identify spectator ions

• Write the complete ionic equation

• Balance the molecular equation

• Check solubility rules

Why is it important to check the solubility of silver compounds?

• Silver compounds are always soluble

• Silver compounds are always insoluble

• Silver compounds can be exceptions to general solubility rules

• Silver compounds do not form precipitates

What is the role of a solubility table in determining the state of a compound?

• It provides the pH of the compound

• It indicates whether a compound is soluble or insoluble

• It determines the molecular weight of the compound

• It helps identify the color of the compound

What are spectator ions?

• Ions that participate in the reaction

• Ions that do not change during the reaction

• Ions that form a precipitate

• Ions that are only present in the products

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

• By adding more ions

• By removing spectator ions

• By balancing the charges

• By changing the states of the compounds

What is the significance of balancing charges in a net ionic equation?

• It confirms the equation is chemically correct

• It ensures the equation is aesthetically pleasing

• It determines the solubility of compounds

• It helps in identifying spectator ions

Why is it unnecessary to write the coefficient '1' in a chemical equation?

• It is only used for solids

• It is a convention to simplify the equation

• It is only used for gases

• It makes the equation incorrect

What happens to the net charge of the reactants and products in a balanced net ionic equation?

• The net charge is positive

• The net charge is negative

• The net charge is zero

• The net charge is variable

What is the final step in verifying a net ionic equation?

• Ensuring the charges and atoms are balanced

• Checking the solubility of products

• Identifying spectator ions

• Writing the complete ionic equation

What is the result of reducing coefficients in a net ionic equation?

• It alters the chemical reaction

• It changes the solubility of compounds

• It simplifies the equation

• It makes the equation more complex
