Molecular Weight: 61.83
CAS No.: 10043-35-3
EINECS: 233-139-2
▏Properties
Boric acid is visually identifiable as a white odorless solid. However, as visual identification is often the least accurate in identifying a substance with accuracy, boric acid is usually identified by its solubility in water and 185℃ melting point using a combination of solute separation techniques and fractional distillation. Boric acid will degrade through dehydration into metaboric acid and tetraboric acid at 171℃ and 300℃, respectively. The density is 1.435g/mL. Its melting point is 185℃.
