Net Ionic Equations and Solubility

The video tutorial explains how to write and balance the net ionic equation for the reaction between calcium phosphate and sulfuric acid. It covers balancing the molecular equation, determining the states of substances, and writing the net ionic equation. The tutorial emphasizes the importance of balancing charges and atoms, and highlights that weak acids and solids are not split in net ionic equations.

What is the first step in balancing the molecular equation for the reaction between calcium phosphate and sulfuric acid?

• Balance the number of phosphate ions.

• Balance the number of hydrogen atoms.

• Balance the number of calcium atoms.

• Balance the number of sulfur atoms.

Why is calcium sulfate considered a solid in the reaction?

• Because it is an exception to the solubility of sulfates.

• Because it is highly soluble.

• Because it is a weak base.

• Because it is a strong acid.

Which of the following substances is not split into ions in the net ionic equation?

• Calcium sulfate

• Phosphoric acid

• Calcium phosphate

• Sulfuric acid

What is the net charge on both sides of the net ionic equation?

• Negative on the reactant side and positive on the product side.

• Positive on the reactant side and negative on the product side.

• Zero on both sides.

• Positive on both sides.

Why are solids and weak acids not split in net ionic equations?

• Because they do not dissociate into ions.

• Because they are not reactive.

• Because they are not part of the reaction.

• Because they do not dissolve in water.
