Ammonia and Net Ionic Equations

This video tutorial explains how to write a balanced net ionic equation for the reaction between ammonia (NH3) and hydroiodic acid (HI). It begins with balancing the molecular equation and identifying the states of each substance. The tutorial then covers splitting strong electrolytes into ions to form the complete ionic equation. Spectator ions are removed to derive the net ionic equation. Additionally, the video discusses the reaction of ammonia with water to form ammonium hydroxide (NH4OH) and provides insights into alternative net ionic equations.

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

• Write the complete ionic equation

• Balance the molecular equation

• Determine the states of substances

• Identify spectator ions

Which of the following is true about hydroiodic acid in the reaction?

• It is a weak acid

• It does not dissociate in water

• It forms a precipitate

• It is a strong acid and dissociates completely

Why is ammonia not split into ions in the net ionic equation?

• It forms a precipitate

• It is a weak base and weak electrolyte

• It is not soluble in water

• It is a strong electrolyte

What is the charge of the ammonium ion?

• 2+

• 1-

• 1+

• 0

Which ion is considered a spectator ion in this reaction?

• Ammonium ion

• Hydrogen ion

• Hydroxide ion

• Iodide ion

What is the significance of the net ionic equation?

• It shows all ions present in the solution

• It highlights the ions that do not participate in the reaction

• It focuses on the ions that participate in the reaction

• It is the same as the molecular equation

What is the charge balance in the net ionic equation for ammonia and hydroiodic acid?

• Positive on one side and negative on the other

• Neutral on both sides

• Negative on both sides

• Positive on both sides

What happens to ammonia when it is dissolved in water?

• It forms a strong acid

• It reacts to form ammonium hydroxide

• It remains unchanged

• It forms a precipitate

What is the nature of the reaction between ammonia and water?

• It forms a strong base

• It is an equilibrium reaction

• It is a complete dissociation

• It does not occur

How does the net ionic equation for ammonium hydroxide differ from the one for ammonia?

• It is the same as the ammonia equation

• It involves different spectator ions

• It involves different reactants

• It is not possible to write
