Net Ionic Equations and Spectator Ions

The video tutorial explains how to balance a net ionic equation for the reaction between calcium nitrate and ammonium carbonate. It begins with balancing the molecular equation and then determining the states of each substance using solubility rules. The tutorial proceeds to split strong electrolytes into ions for the complete ionic equation, while leaving solids intact. 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 balancing a net ionic equation?

• Determine the solubility of compounds

• Balance the molecular equation

• Identify spectator ions

• Split strong electrolytes into ions

According to solubility rules, which of the following is generally insoluble?

• Ammonium compounds

• Sodium chloride

• Calcium carbonate

• Nitrates

What happens to strong electrolytes in the complete ionic equation?

• They are removed as spectator ions

• They form a precipitate

• They remain as whole compounds

• They are split into ions

Why are solids not split into ions in net ionic equations?

• They are spectator ions

• They do not dissolve in water

• They are already balanced

• They are not strong electrolytes

What is the role of spectator ions in a chemical reaction?

• They participate in forming the precipitate

• They balance the charges

• They do not participate in the reaction

• They change the state of the reactants

Which ions are removed to find the net ionic equation?

• All ions

• Only the ions forming a precipitate

• Ions with a positive charge

• Spectator ions

What must be balanced in the final net ionic equation?

• Only the coefficients

• Only the atoms

• Only the charges

• Both atoms and charges

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

• Depends on the reactants

• Positive

• Negative

• Zero

Which of the following is a characteristic of a neutral compound in a net ionic equation?

• It has a net positive charge

• It has a net negative charge

• It has a net charge of zero

• It contains only spectator ions

What is the final product of balancing a net ionic equation?

• A complete ionic equation

• A balanced net ionic equation

• A balanced molecular equation

• A list of spectator ions
