Name a crystal-like, white compound with strong pungent aroma and taste, which is purified by the process of sublimation.

The Correct answer is Camphor.

Key Points

• Camphor is a white, crystalline compound that has a strong, pungent aroma and taste.
• It is commonly obtained from the wood of the camphor tree (Cinnamomum camphora), which is native to Asia.
• The compound is purified by the process of sublimation, where it transitions directly from a solid to a gaseous state without passing through a liquid phase.
• Camphor is widely used for its medicinal properties, such as in the treatment of coughs, colds, and skin irritations.
• It is also used in religious rituals and as a key ingredient in some aromatic products, such as incense and balms.
• Camphor has a cooling effect and is used in topical applications to relieve pain and inflammation.
• Its strong aroma is effective in repelling insects, making it a common choice for use in mothballs and insect repellents.

  • Lye is a strong alkaline compound, primarily composed of sodium hydroxide (NaOH) or potassium hydroxide (KOH).
  • It is commonly used in the production of soap, cleaning agents, and in food preparation, such as curing olives and making pretzels.
  • Lye is highly corrosive and does not possess the aromatic properties or the ability to undergo sublimation like camphor.
• Caustic Potash
  • Caustic Potash is another name for potassium hydroxide (KOH), a strong base.
  • It is used in soap making, fertilizers, batteries, and as an electrolyte in certain applications.
  • Unlike camphor, it does not exhibit a strong aroma or undergo sublimation.
• Soda Ash
  • Soda Ash, also known as sodium carbonate (Na₂CO₃), is a water-soluble salt.
  • It is primarily used in the production of glass, detergents, and paper.
  • Soda Ash lacks the characteristic strong aroma and sublimation properties of camphor.
