Question

When would communicating a chemical change through a molecular equation be better than an ionic or net ionic equation?

• A. When there are spectator ions present.
• B. When determining the conductivity changes of a reaction.
• C. When none of the substances are soluble.
• D. When no solids, liquids or gases are formed.

Answer 1

The correct option is A When there are spectator ions present.

The net ionic equation shows only the chemical species that are involved in a reaction, while the complete ionic equation also includes spectator ions

When there are spectator ions present.
