Question
Which of the following are spectator ions in the given reaction Na2CO3(aq) + 2AgNO3(aq) ⟶ Ag2CO3(s) + 2NaNO3(aq) Select an answerA Na+ and NO3− B Na+ and NO32− C CO3− and Ag+ D CO32− and NO3−
Solution
Spectator ions are ions that exist in the same form on both the reactant and product side of a chemical equation. They do not participate in the overall reaction, but are present throughout.
In the given reaction, Na2CO3(aq) + 2AgNO3(aq) → Ag2CO3(s) + 2NaNO3(aq), we can break down the compounds into their respective ions:
- Na2CO3(aq) breaks down into 2Na+ and CO3(2-)
- AgNO3(aq) breaks down into Ag+ and NO3-
- Ag2CO3(s) breaks down into 2Ag+ and CO3(2-)
- NaNO3(aq) breaks down into Na+ and NO3-
Comparing the ions on both sides of the equation, we can see that Na+ and NO3- are present on both sides and do not change. Therefore, the spectator ions in this reaction are Na+ and NO3-.
So, the answer is A: Na+ and NO3-.
