Question
Indicate whether each species is a reactant, product or spectator.Dilute hydrochloric acid is added to a solution of sodium carbonate, evolving carbon dioxide.2H+(aq) + 2Cl-(aq) + 2Na+(aq) + CO32-(aq) → CO2(g) + H2O(l) + 2Na+(aq) + 2Cl-(aq)
Solution
In the given reaction:
2H+(aq) + 2Cl-(aq) + 2Na+(aq) + CO32-(aq) → CO2(g) + H2O(l) + 2Na+(aq) + 2Cl-(aq)
Each species plays the following role:
- 2H+(aq): Reactant
- 2Cl-(aq): Spectator ion (it appears unchanged on both sides of the equation)
- 2Na+(aq): Spectator ion (it appears unchanged on both sides of the equation)
- CO32-(aq): Reactant
- CO2(g): Product
- H2O(l): Product
So, H+ and CO32- are reactants, CO2 and H2O are products, and Na+ and Cl- are spectator ions.
