Net Ionic Equations and Solubility

The video tutorial explains how to write a balanced net ionic equation for the reaction between silver nitrate (AgNO3) and iron(III) chloride (FeCl3). It begins with balancing the molecular equation, followed by determining the solubility and states of the substances involved. The tutorial then breaks down the reaction into a complete ionic equation, identifying spectator ions, and finally derives the net ionic equation. The importance of charge and mass conservation is emphasized throughout the process.

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

• Write the complete ionic equation

• Determine the solubility of compounds

• Balance the molecular equation

• Identify the spectator ions

How do you balance the number of nitrate ions in the reaction?

• Add more iron ions

• Add more silver ions

• Adjust the coefficient of AgNO3

• Adjust the coefficient of FeCl3

Which of the following is insoluble in water?

• Silver nitrate

• Silver chloride

• Iron(III) chloride

What is the charge of a silver ion in the complete ionic equation?

• 1-

• 1+

• 3+

• 2+

Why don't we split AgCl in the complete ionic equation?

• It is a strong electrolyte

• It is a weak electrolyte

• It is a solid precipitate

• It is a gas

What is the purpose of removing spectator ions?

• To determine solubility

What is conserved in a net ionic equation?

• Only mass

• Only charge

• Both mass and charge

• Neither mass nor charge

What is the net ionic equation for the reaction between AgNO3 and FeCl3?

• Fe3+ + 3NO3- → Fe(NO3)3

• 3Ag+ + 3Cl- → 3AgCl

• AgNO3 + FeCl3 → AgCl + Fe(NO3)3

• Ag+ + Cl- → AgCl

What happens to the coefficients in the net ionic equation?
