A yellow-colored crystalline solid is associated with which explosive?

The yellow-colored crystalline solid is primarily associated with picric acid, which is a nitrophenol. It is characterized by its bright yellow hue and has been used historically as an explosive compound, particularly during the early 20th century. Picric acid can be formed from the nitration of phenol, and when in its dry form, it is known to be quite sensitive and potentially dangerous.

In the context of explosives, picric acid has properties that make it a high explosive, rivaling that of TNT. Its distinct yellow color helps in its identification, which is significant for safety protocols and handling procedures in explosive storage and usage. Understanding the characteristics of various explosives, including their physical properties, enables proper risk management and safety compliance in security and protection professions.
