Net Ionic Equations and Spectator Ions

This video tutorial explains how to balance net ionic equations, specifically for the reaction between copper(II) hydroxide and hydrochloric acid. It covers writing the balanced molecular equation, determining the states of compounds using a solubility table, and splitting strong electrolytes into ions to form the complete ionic equation. The tutorial concludes with identifying and removing spectator ions to derive the net ionic equation.

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

• Write the complete ionic equation

• Write the balanced molecular equation

• Identify spectator ions

• Determine the states of compounds

Why is it important to check the solubility of hydroxides?

• They are always soluble

• They are always gases

• They are often insoluble, especially with transition metals

• They never dissociate into ions

What does the 's' state symbol indicate for a compound?

• The compound is insoluble

• The compound is a gas

• The compound is soluble

• The compound is aqueous

Which of the following is a strong electrolyte?

• Copper(II) hydroxide

• Hydrochloric acid

• Water

• Copper(II) oxide

What charge does a chlorine ion typically have?

• Positive

• Negative

• Variable

• Neutral

What is the purpose of splitting compounds into ions?

• To balance the equation

• To identify the molecular equation

• To form the complete ionic equation

• To determine the solubility

What are spectator ions?

• Ions that form a precipitate

• Ions that are gases

• Ions that change state during the reaction

• Ions that do not participate in the reaction

Which ions are removed to form the net ionic equation?

• Only negative ions

• Spectator ions

• All ions

• Only positive ions

What should be done after writing the net ionic equation?

• Write the states for each compound

• Check the solubility again

• Rebalance the molecular equation

• Identify new spectator ions

What is the final step in balancing net ionic equations?

• Checking the periodic table

• Reviewing the process

• Crossing out all ions

• Writing the complete ionic equation
