Question
Indicate whether each species is a reactant, product or spectator.Dilute nitric acid is added to solid sodium carbonate, evolving carbon dioxide.
Solution
The reaction between dilute nitric acid and solid sodium carbonate can be represented by the following balanced chemical equation:
2HNO3(aq) + Na2CO3(s) --> 2NaNO3(aq) + H2O(l) + CO2(g)
In this reaction:
- Dilute nitric acid (HNO3) is a reactant because it is consumed in the reaction.
- Solid sodium carbonate (Na2CO3) is also a reactant because it is consumed in the reaction.
- Carbon dioxide (CO2) is a product because it is produced by the reaction.
- Sodium nitrate (NaNO3) is a product because it is produced by the reaction.
- Water (H2O) is a product because it is produced by the reaction.
There are no spectator ions in this reaction. Spectator ions are ions that exist in the same form on both the reactant and product sides of a chemical equation. They do not participate in the reaction.
