What is Boric Acid?
This is a weak inorganic acid with multiple antiseptic properties and the chemical formula for the substance could be written as H3BO3 with a molar mass 61.83 g/mol. The structure of the molecule is also given below where central boron atom is connected to 3 hydroxyl groups and capable in strong hydrogen building.
Boric Acid Structure
Further, the compound has solid crystalline structure consist of parallel layer of boric acid and help together to form hydrogen bonds in place.
Boric Acid Chemical Formula
The natural occurrence of the boric acid can be felt in volcanic areas and certain minerals like borax. It is also available in the sea water, fruits, plants etc in a little quantity only. The acid is crystalline in nature with a density of 1.435 g/mL and a melting point of 170.9 degree Celsius and a boiling point of 300 degree Celsius.
Na2B4O7·10H2O + 2 HCl → 4 H3BO3 + 2 NaCl + 5 H2O
H3BO3 → HBO2 + H2O
Boric Acid Properties
This is a monobasic acid and considered as the Lewis acid too. It dissolves in water quickly if it is boiled and it undergoes dehydration at high temperatures. The boric acid is generally non-toxic in nature with antibacterial properties and can be used as an antiseptic agent too. It is used for acne treatment, swimming pools, insecticides or pesticides etc.
Further, it is used for the manufacturing of fiberglass and many other useful chemicals. It is also used in glasses that are used for LCD displays. Because of the low concentration of the chemical, it does not pose any toxicity but could be dangerous when inhaled in large quantities.
