Solubility and Ionic Equations

The video tutorial explains how to balance net ionic equations, starting with balancing the molecular equation. It covers the solubility of compounds, splitting strong electrolytes into ions, and identifying spectator ions. The tutorial emphasizes the importance of conserving charge and balancing atoms in the final net ionic equation.

What is the first step in balancing net ionic equations?

• Identify spectator ions

• Balance the molecular equation

• Determine the solubility of compounds

• Write the net ionic equation

What do you do with strong electrolytes in the complete ionic equation?

• Split them into ions

• Combine them

• Convert them to gases

• Ignore them

What are spectator ions?

• Ions that are gases

• Ions that participate in the reaction

• Ions that do not change during the reaction

• Ions that form a precipitate

Which ions are crossed out in the net ionic equation?

• All ions

• Spectator ions

• Product ions

• Reactant ions

What is conserved in a balanced net ionic equation?

• Neither mass nor charge

• Both mass and charge

• Charge only
