Chemical Reactions and Aqueous Solutions

The video tutorial explains how to write a balanced net ionic equation for the reaction between ammonium phosphate and sodium sulfate. It begins by balancing the molecular equation, ensuring equal numbers of ions on both sides. The solubility of compounds is discussed, highlighting that all substances are aqueous and dissociate into ions. Since no new substances are formed, no net ionic equation can be written, as no reaction occurs. The tutorial concludes with a summary of the process.

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

• Identify the spectator ions

• Balance the molecular equation

What does it mean when a compound is described as aqueous?

• It is a liquid

• It is a solid

• It is a gas

• It is dissolved in water

What happens to the ions in an aqueous solution?

• They combine to form a new compound

• They remain as separate ions

• They form a solid precipitate

• They evaporate

Why can't a net ionic equation be written for the reaction between ammonium phosphate and sodium sulfate?

• A precipitate forms

• A gas is released
