Potassium bromide (KBr) powder is a fine white crystalline substance with a granular texture. It typically appears as a dry, free-flowing powder, though it can also be found in larger crystalline forms. KBr is odorless and has a salty taste. It is highly soluble in water, meaning it readily dissolves in aqueous solutions.
Under normal conditions, KBr is stable and non-reactive, but it should be stored in airtight containers to prevent moisture absorption, which can cause clumping or caking of the powder. It has a relatively high melting point of 734°C (1353°F) and does not decompose at typical handling temperatures.
When handling KBr powder, it’s important to take appropriate safety precautions, as with any chemical substance. This may include wearing gloves, protective eyewear, and a dust mask to prevent inhalation of fine particles. Proper ventilation is also recommended when working with KBr powder to minimize exposure to airborne particles.
