When Nitric Acid Is Added to Eggshells

What Happens When Nitric Acid is Added to Eggshells? Give a Reason for your Observation.

Calcium carbonate is the primary component of eggshells. Lime water has a milky appearance as a result of the gas that is produced during this reaction. Now give it your best shot to respond appropriately.

Calcium carbonate is the primary component of eggshells. Nitric acid combines with calcium carbonate, which is already present in the egg-shell, to produce calcium nitrate, as well as water and carbon dioxide gas. This reaction takes place when egg-shell is added to nitric acid.

Lime water becomes milky as a result of the production of carbon dioxide gas from this process.

Additionally, the equation that describes this process may be written down here.

CaCO3(s)+2HNO3(aq)→Ca(NO3)2(aq)+CO2(g)+H2O(l)

Calcium nitrate, carbon dioxide, and water are the products of the reaction between eggshells and nitric acid.

As a result, we went over the process of what happens when eggshells are exposed to nitric acid.

Calcium nitrate is one of the compounds that we can observe here due to the reaction. Calcium nitrate is primarily manufactured for use as a fertilizer and in wastewater treatment. Plants may obtain calcium and nitrogen from calcium nitrate as a source of these elements. This carbon dioxide created here will dissolve in water and eventually produce carbonic acid through its reaction with water.

When carbon dioxide is bubbled into limewater, a hazy white solution is seen as a result of a reaction between calcium hydroxide (Ca(OH)2) and either carbon dioxide (CO2) or hydrogen carbonate (H2CO3), which results in the formation of an insoluble calcium carbonate precipitate.
