Introduction

---

Boric acid, also called boracic acid or Orthoboric acid or Acidum Boricum, When occurring as a mineral, it is called sassolite.it is a weak acid ,often used as an antiseptic, insecticide, flame retardant, in nuclear power plants to control the fission rate of URANIUM, and as a precursor of other chemical compounds. It exists in the form of colorless crystals or a white powder and dissolves in water.

Boric acid is soluble in boiling water. When heated above 170°C it dehydrates, forming metaboric acid HBO2, a white, cubic crystalline solid and is only slightly soluble in water. when heated above about 300°C further dehydrates, forming tetraboric acid or pyroboric acid, H2B4O7. Boric acid can refer to any of these compounds. Further heating leads to BORON trioxide.
