Net Ionic Equations and Spectator Ions

The video tutorial explains how to write a balanced net ionic equation for the reaction between manganese(II) chloride and ammonium carbonate. It begins by balancing the molecular equation, then discusses solubility rules to determine the states of the compounds involved. The tutorial proceeds to form the complete ionic equation, identifying and removing spectator ions to derive the net ionic equation. Finally, it verifies the balance of charges and atoms in the net ionic equation.

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

• Split strong electrolytes into ions

• Identify spectator ions

• Balance the molecular equation

• Determine the states of compounds

How do you balance the number of ammonium ions in the equation?

• Remove one ammonium ion

• Add a coefficient of 3 in front of ammonium carbonate

• Add a coefficient of 2 in front of ammonium chloride

• Add a coefficient of 2 in front of manganese chloride

Which of the following is generally insoluble unless bonded to an ammonium ion?

• Chlorides

• Carbonates

• Sulfates

• Nitrates

What happens to manganese II carbonate in the reaction?
