Net Ionic Equations Review

What do ionic equations show in a chemical reaction?

• The color change of the solution

• The details of a reaction involving ions in aqueous solutions

• The temperature change during the reaction

• The pH level of the solution

What is a complete ionic equation?

• An equation that shows all of the particles in a solution as they exist, including amounts.

• An equation that includes only the particles that participate in the reaction.

• An equation that shows only the products of a reaction.

• An equation that excludes spectator ions.

What is a net ionic equation?

• An equation that shows all of the particles in a solution.

• An equation that includes only the particles that participate in the reaction.

• An equation that includes spectator ions.

• An equation that shows the physical state of all reactants.

Which compounds are split into ions in an ionic equation?

• Solid compounds

• Gaseous compounds

• Aqueous compounds

• Liquid compounds

What ions are always soluble and therefore always receive an (aq) physical state?

Only list the ions that DO NOT have exceptions according to the solubility rules.

When breaking up aqueous compounds, what must be included for each ion in an ionic equation?

• The formula of the ion.

• The charge of the ion.

• The coefficient of the ion that has accounted for any subscripts.

• The physical state of the ion from the balanced equation.

• All of the above.

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

• Write the complete ionic equation.

• Cross out spectator ions.

• Write the balanced chemical equation.

• Write the remaining ions.

Which step involves removing ions that appear on both sides of the equation?

• Write the balanced chemical equation.

• Write the complete ionic equation.

• Cross out spectator ions.

• Write the remaining ions.

What are spectator ions?

• Ions that participate in the reaction.

• Ions that do not participate in the reaction and appear on both sides of the yield sign.

• Ions that are only present in the reactants.

• Ions that are only present in the products.

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

• Write the balanced chemical equation.

• Write the complete ionic equation.

• Cross out spectator ions.

• Write the remaining ions.
