Net Ionic Equations and Spectator Ions

The video tutorial explains how to write a balanced net ionic equation for the reaction between sodium acetate and hydrochloric acid. It begins with balancing the molecular equation, then discusses the solubility and states of the substances involved. The tutorial proceeds to split strong electrolytes into ions to form the complete ionic equation, while weak acids like acetic acid remain intact. Spectator ions are removed to derive the net ionic equation, ensuring that charges and atoms are balanced. The tutorial concludes with a summary of the process and key points.

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

• Balance the molecular equation

• Identify spectator ions

• Determine the solubility of compounds

• Split strong electrolytes into ions

Which of the following compounds is considered very soluble?

• Lead sulfate

• Silver chloride

• Sodium acetate

What is the state of sodium chloride in the reaction?

• Solid

• Liquid

• Gas

• Aqueous

Which of the following is a strong acid?

• Carbonic acid

• Hydrochloric acid

• Phosphoric acid

• Acetic acid

Why do we not split weak acids in net ionic equations?

• They are strong acids

• They do not ionize at all

• They are insoluble

• They ionize only slightly

What is the purpose of identifying spectator ions in a reaction?

• To identify strong acids

• To determine solubility

• To simplify the net ionic equation

• To balance the charge

Which ion is a spectator ion in the reaction between sodium acetate and hydrochloric acid?

• Sodium ion

• Chloride ion

• Acetate ion

• Hydrogen ion

What happens to the chloride ion in the net ionic equation?

• It forms a precipitate

• It remains as a spectator ion

• It forms a gas

• It reacts with sodium

What ensures that a net ionic equation is correctly balanced?

• Presence of spectator ions

• Equal number of atoms on both sides

• All acids are strong

• All compounds are soluble

What is the charge of the acetic acid molecule in the net ionic equation?

• Negative

• Neutral

• Positive

• Variable
