Introduction:
The given question states that the white of an egg turns violet when two drops of copper sulphate and ten drops of caustic soda are added to it. This color change indicates the presence of a specific component of food. Let's understand why the correct answer is option 'B' - Proteins.
Explanation:
1. Composition of egg white:
Egg white, also known as albumen, is primarily composed of proteins. It contains water, proteins, vitamins, and minerals. The proteins in egg white are responsible for its structure and texture.
2. Copper Sulphate and Caustic Soda:
Copper sulphate and caustic soda are the chemicals added to the egg white in the given scenario. These chemicals are used as reagents to test for the presence of specific components in foods.
3. Copper Sulphate Test:
The addition of two drops of copper sulphate to the egg white is a test known as the Biuret Test. In this test, copper sulphate reacts with proteins and forms a complex with them. This complex has a characteristic violet color.
4. Caustic Soda:
The addition of ten drops of caustic soda helps in enhancing the color change. Caustic soda is an alkaline substance that increases the pH of the solution. This change in pH facilitates the reaction between copper sulphate and proteins, resulting in a more intense violet color.
5. Presence of Proteins:
Since the white of an egg turns violet when the given chemicals are added, it indicates the presence of proteins in the egg white. This is because proteins are the only component in the egg white that reacts with copper sulphate to produce a violet color.
Conclusion:
In conclusion, the correct answer is option 'B' - Proteins. The violet color observed after adding copper sulphate and caustic soda to the egg white indicates the presence of proteins. This color change is a result of the reaction between copper sulphate and proteins, forming a complex with a characteristic violet color.
