Net Ionic Equations and Precipitation

This video tutorial explains how to write a balanced net ionic equation for the reaction between silver nitrate and ammonium carbonate. It covers balancing the molecular equation, determining the states of substances using solubility rules, writing the complete ionic equation, and identifying spectator ions to derive the net ionic equation. The tutorial emphasizes the importance of charge balance and highlights the formation of a precipitate, silver carbonate, in the reaction.

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

• Determine the solubility of compounds

• Identify spectator ions

• Write the complete ionic equation

What state symbol is used for a substance that forms a precipitate?

• (g)

• (s)

• (l)

• (aq)

What is the charge of a nitrate ion?

• 1+

• 1-

• 2-

Why do we not split solids into ions in the complete ionic equation?

• They are already balanced

• They are spectator ions

• They do not dissolve in water

• They are not electrolytes

What are spectator ions?

• Ions that participate in the reaction

• Ions that are insoluble

• Ions that do not change during the reaction

• Ions that form a precipitate

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

• 2+

• 2-

• 0

• 1+

Which compound is the precipitate in the reaction?
