FeCO₃(s) + 2 HCOOH(aq) → Fe(HCOO)₂(aq) + CO₂(g) + H₂O(l)
Here's a breakdown of the reaction:
* Iron carbonate (FeCO₃): A solid compound that is the reactant.
* Formic acid (HCOOH): A weak organic acid in aqueous solution (dissolved in water), also a reactant.
* Iron formate (Fe(HCOO)₂): A soluble iron salt formed as a product. It dissolves in water to form ions.
* Carbon dioxide (CO₂): A colorless gas produced as a product.
* Water (H₂O): A liquid produced as a product.
Explanation:
The reaction is a double displacement reaction, where the iron in iron carbonate is replaced by the hydrogen from formic acid. Formic acid is a weak acid, meaning it does not completely dissociate in solution. However, it's still strong enough to react with the iron carbonate.
Key observations:
* Gas evolution: You will observe the formation of bubbles due to the release of carbon dioxide gas.
* Solution color change: Depending on the concentration of the reactants, the solution may become slightly cloudy or change color due to the formation of iron formate.
