Can someone make sure I have the right answer. The question is: Classify the statement as always true, sometimes true, or never true.

A net ionic equation shows all ions present.
I say never true because it only shos soluble strong electrolytes reacting and not spectator ions. Thanks

I cant think of when it would be sometime true. You are correct.

Thank you for your time. Have a good night.

You are correct! The statement "A net ionic equation shows all ions present" is never true. A net ionic equation only includes the ions that participate in a chemical reaction and are directly involved in the formation of a product. It excludes spectator ions, which are present in the reaction mixture but do not undergo any change during the reaction.

To verify this, we can break down the components of a net ionic equation.

1. Start with a balanced molecular equation that represents the overall reaction, including all reactants and products in their fully written-out forms.

2. Identify the soluble strong electrolytes among the reactants, as these are the ones that ionize completely in solution to form ions.

3. Write the complete ionic equation by representing each strong electrolyte as separate ions. Include their appropriate charges.

4. Cancel out and eliminate any spectator ions that appear on both sides of the equation. These ions do not undergo any chemical change and are not involved in the formation of the products.

5. Finally, write the net ionic equation by eliminating the spectator ions from the complete ionic equation. This equation only shows the ions that are directly involved in the chemical reaction.

Therefore, a net ionic equation does not show all ions present, but rather only the ions that are involved in the reaction itself.
