Preparation of Boric Acid:

• It is prepared by reacting borax (sodium tetraborate decahydrate) with a mineral acid such as hydrochloric acid:

$\mathrm{Na_2B_4O_7 \cdot 10H_2O + 2HCl \rightarrow 4H_3BO_3 + 2NaCl + 5H_2O}$

Properties of Boric Acid:

• White, odorless crystalline powder.
• Slightly soluble in cold water and more soluble in hot water.
• Weakly acidic, with mild antiseptic and antifungal properties.
• Chemical formula: H₃BO₃.

Uses:

• As an antiseptic for minor cuts and burns.
• In ophthalmic preparations to treat eye infections.
• As a buffering agent in various pharmaceutical formulations.
