Solubility and Ionic Reactions

The video tutorial explains how to write a balanced net ionic equation for the reaction between silver nitrate (AgNO3) and potassium carbonate (K2CO3). It begins with balancing the molecular equation, followed by determining the states of each compound using solubility rules. The tutorial then breaks down the compounds into ions to form the complete ionic equation and identifies spectator ions to derive the net ionic equation. The video concludes by ensuring the charge is balanced and the atoms are accounted for, providing a clear understanding of the process.

What is the first step in writing a balanced molecular equation for a reaction?

• Identify the spectator ions.

• Determine the solubility of the compounds.

• Balance the number of atoms for each element.

• Write the net ionic equation.

Which of the following compounds is generally soluble in water?

Why are silver compounds often considered insoluble?

• They react with water to form gases.

• They are covalent compounds.

• They have a high molecular weight.

• They form strong ionic bonds that do not dissociate easily.

Which of the following is a characteristic of a precipitation reaction?

• Formation of a gas

• Emission of light

• Formation of a solid

• Change in color

What is the role of solubility rules in writing net ionic equations?

• To balance the molecular equation

• To predict the formation of a precipitate

• To identify the spectator ions

• To determine the charge of ions

What is the charge of a silver ion in the context of this reaction?

• 1+

• 2+

• 2-

• 1-

In the complete ionic equation, which ions are considered spectator ions?

• Silver ions and nitrate ions

• Potassium ions and nitrate ions

• Potassium ions and carbonate ions

• Silver ions and carbonate ions

What happens to the spectator ions in a net ionic equation?

• They are removed from the equation.

• They form a precipitate.

• They change their charge.

• They are included in the final equation.

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

• Positive on both sides

• 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

How do you ensure that a net ionic equation is balanced?

• By checking that the number of atoms and the charge are balanced

• By balancing only the charges

• By ensuring all compounds are soluble

• By including all spectator ions
