Boric Acid, also called Boracic Acid or Orthoboric Acid, is a mild acid that exists in the
form of colorless crystals or a white powder and dissolves in water.
Available in crystalline (granular) or powder form, Boric Acid has the chemical formula H3BO3, sometimes written B(OH)3. When occurring as a mineral, it is called Sassolite.
Chemical Composition - TYPICAl
PHYSICAL PROPERTIES & SIZE DISTRIBUTION - CRYSTALLINE
