Balancing Ionic Equations and Solubility

This video tutorial explains how to balance net ionic equations, starting with balancing the molecular equation for silver nitrate and aluminum chloride. It covers writing the states of substances using solubility rules, splitting strong electrolytes into ions for the complete ionic equation, and identifying spectator ions to derive the net ionic equation. The tutorial emphasizes the importance of balancing charges and atoms to achieve a neutral net charge.

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

• Write the states of each substance

• Identify spectator ions

• Balance the molecular equation

• Determine the solubility of compounds

When balancing the molecular equation, what should you do if there are three chlorines on one side and only one on the other?

• Add a coefficient of two to the compound with one chlorine

• Add a coefficient of three to the compound with three chlorines

• Remove two chlorines from the side with three

• Add a coefficient of three to the compound with one chlorine

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

• Nitrates

• Chlorides

• Aluminum chloride

• Silver chloride

What is the state of a compound that is insoluble in water?

• Liquid

• Solid

• Gaseous

• Aqueous

What charge does a silver ion typically have?

• 1+

• 1-

• 2+

• 3+

In the complete ionic equation, which ions are not split apart?

• Aqueous ions

• Solid compounds

• Gaseous compounds

• Liquid compounds

What are spectator ions?

• Ions that form a precipitate

• Ions that participate in the reaction

• Ions that are insoluble

• Ions that do not change during the reaction

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

• Positive

• Negative

• Depends on the reaction

• Zero

What should be done if the same coefficient is in front of each compound in the net ionic equation?

• Change the coefficients to zero

• Reduce the coefficients to one

• Leave the coefficients as they are

• Increase the coefficients

Why is it important to ensure that the atoms are balanced in a net ionic equation?

• To maintain the law of conservation of mass

• To ensure the reaction is spontaneous

• To increase the reaction rate

• To decrease the reaction rate
