Correct Question:
A spectator ion is (Select all that apply.)
- a piece of french fry contaminating the reaction mixture
- an ionic component of a reactant that is unchanged by the reaction
-in this experiment, nitrate ion
- your eye, carefully watching the progress of the reaction
Answer:
- an ionic component of a reactant that is unchanged by the reaction
Explanation:
A spectator ion is an ion that exists as a reactant and a product in a chemical equation. A spectator ion is one that exists in the same form on both the reactant and product sides of a chemical reaction.
Spectator ions are ions that are present in a solution but don't take part in the reaction. When reactants dissociate into ions, some of the ions may combine to form a new compound. The other ions don't take part in this chemical reaction and are therefore called spectator ions.
The correct option is therefore the option;
- an ionic component of a reactant that is unchanged by the reaction
