The chemical equation FeCO3 + HNO3 -> Fe(NO3)2 + CO2 + H2O

Detailed information about the equation FeCO₃ + HNO₃ -> Fe(NO₃)₂ + CO₂ + H₂O
This is a chemical reaction that occurs between the compound FeCO₃ (Siderite – a type of salt of carbonic acid with iron) and the acid HNO₃ (Nitric Acid), producing Fe(NO₃)₂ (Iron(II) Nitrate), CO₂ (carbon dioxide gas) and H₂O (water).

Reaction conditions
This reaction typically occurs when the reactants are in direct contact with each other in an appropriate environment. The specific conditions for the reaction can be adjusted based on the specific requirements of the experiment such as temperature, pressure, the amount of reactants, etc.

Reaction Process
The reaction process takes place when FeCO₃ comes into contact with HNO₃, meaning the molecules of these two substances start interacting with each other. In this process, the iron atom in FeCO₃ combines with the nitrate ions in nitric acid to form iron(II) nitrate, while the carbonate ions in siderite combine with the hydrogen ions from nitric acid to form carbon dioxide gas and water.

Phenomena that occur
Based on the chemical equation, the phenomena that can be predicted to occur during the reaction is the release of CO₂ gas, usually observed as gas bubbles escaping from the solution. Simultaneously, the solution also transitions to containing iron(II) nitrate.
