Understanding the Detection of Carbon and Hydrogen
The detection of carbon and hydrogen in organic compounds typically involves combustion, leading to the formation of carbon dioxide and water. However, the focus shifts to precipitation in this context.
Precipitation in the Detection Process
During the detection process, we are primarily concerned with the identification of carbon. When an organic compound is combusted in excess oxygen, carbon is oxidized to form carbon dioxide (CO2).
Role of Calcium Carbonate
In this specific context, calcium carbonate (CaCO3) plays a critical role:
- When carbon dioxide is produced, it can react with calcium hydroxide (limewater) to form calcium carbonate, which is insoluble in water.
- The formation of a white precipitate indicates the presence of carbon in the original sample.
Why Other Options Do Not Precipitate
- a) Copper: This metal does not precipitate during the detection of carbon and hydrogen.
- b) Carbon Dioxide: While CO2 is produced, it does not precipitate; instead, it remains in a gaseous state.
- d) Copper Sulphate: This is a soluble compound and does not participate in the precipitation relevant to carbon detection.
Conclusion
Thus, calcium carbonate is the compound that precipitates when detecting carbon and hydrogen, confirming option 'C' as the correct answer. This precipitate serves as a visual indication of carbon's presence in the initial compound.

Calcium carbonate (CaCO3) gets precipitated during the detection of carbon and hydrogen. Firstly carbon will react with copper (II) oxide to form copper and carbon dioxide. Then, hydrogen will react with the same copper (II) oxide to form copper and water. After this, the presence of carbon dioxide is tested by reacting it with calcium hydroxide and the product obtained is calcium carbonate, which gets precipitated and water.
