Carbon Dioxide, CO2.
If nitric acid is mixed with calcium carbonate, carbon dioxide gas would be produced along with calcium nitrate and water.
carbon dioxide
The gas carbon dioxide is released.
When nitric acid reacts with calcium carbonate, carbon dioxide gas is produced. The chemical equation for this reaction is: 2HNO3 + CaCO3 -> Ca(NO3)2 + CO2 + H2O.
Calcium Carbonate + Hydrogen Nitrate -> Calcium Nitrate + Carbon Dioxide + Water
When calcium carbonate reacts with dilute nitric acid, calcium nitrate, carbon dioxide gas, and water are formed. This is a double displacement reaction where the calcium in the calcium carbonate is replaced by the nitrate ion from the nitric acid. The balanced chemical equation for the reaction is: CaCO3(s) + 2HNO3(aq) -> Ca(NO3)2(aq) + CO2(g) + H2O(l)
When nitric acid is added to egg shell, it releases nitrogen dioxide gas. This reaction is a result of the acid reacting with the calcium carbonate in the eggshell to produce calcium nitrate, water, and nitrogen dioxide gas.
To test the reaction between calcium carbonate and nitric acid, you can observe the formation of bubbles (carbon dioxide gas being released) and the effervescence in the reaction mixture. You can also test for the presence of carbon dioxide by passing the gas through limewater, which will turn milky due to the formation of calcium carbonate precipitate. Additionally, you can measure the pH of the solution before and after the reaction, as nitric acid is acidic and will lower the pH.
When marble, which is primarily composed of calcium carbonate, is introduced to sulfuric or nitric acid, carbon dioxide gas is produced. This is due to a chemical reaction that releases the gas from the decomposition of the calcium carbonate in the marble.
Calcium carbonate reacts with acid rain because the acid in the rain, typically sulfuric acid or nitric acid, causes a chemical reaction that breaks down the calcium carbonate into its component ions, releasing carbon dioxide gas. This reaction forms soluble calcium ions, which can then be carried away in the water.
Chalk is calcium carbonate (CaCO3) thus addition of dilute acid will produce carbon dioxide and a calcium salt. E.g. addition of dilute hydrochloric acid will produce CO2 and calcium chloride (CaCl2).
