Net Ionic Equations and Solubility

The video tutorial explains how to write and balance net ionic equations, using lithium phosphate and magnesium sulfate as examples. It begins with balancing the molecular equation, then moves on to balancing the net ionic equation by identifying the states of substances and removing spectator ions. The tutorial concludes with verifying the balanced net ionic equation, ensuring charge and atom balance.

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

What is the role of spectator ions in a chemical reaction?

• They remain unchanged and do not participate

• They participate in the reaction

• They balance the charge of the reaction

• They change the state of the reaction

Which ions are considered spectator ions in the reaction between lithium phosphate and magnesium sulfate?

• Lithium and sulfate ions

• Magnesium and phosphate ions

• Only lithium ions

• Only sulfate ions

What is the net charge of the final net ionic equation?

• Depends on the reactants

• Negative

• Positive

• Zero

Why is it important to ensure that the charge is balanced in a net ionic equation?

• To ensure the reaction is spontaneous
