Boric acid is easily soluble in water without any special smell. Under standard conditions, the compound exists as colorless crystals or white powder. Boric acid can be prepared by reacting borax with hydrochloric acid. It may be noted that Wilhelm Homberg was the first to prepare boric acid from borax.
boric acid in medicine
Boric acid is widely used as an antiseptic in the treatment of minor cuts and burns. Additionally, the compound is used in medical dressings and ointments. A very dilute solution of boric acid can be used as an eyewash. Due to its antibacterial properties, boric acid is also used to treat acne in humans. In powder form it can also be sprinkled on socks and shoes to prevent athlete's foot (tinea pedis).

It's important to note that boric acid can be toxic if eaten or inhaled in large quantities. Additionally, prolonged and sustained exposure to boric acid can severely damage the kidneys.

Preparation of boric acid
One of the easiest ways to prepare boric acid is to react borax with any mineral acid such as hydrochloric acid. The chemical equation for this reaction can be written as:

Na2B4O7.10H2O + 2HCl ? 4H3BO3 + 5H2O + 2NaCl

Boronic acid can also be prepared by hydrolysis of diborane and boron trihalides (such as boron trichloride or boron trifluoride).
Under standard temperature and pressure (STP) conditions, boric acid exists as a white crystalline solid that is very soluble in water. The solubility of H3BO3 in water is temperature dependent. The solubility of boric acid in water at 25 °C is 57 g/L. However, when water is heated to 100 °C, the solubility of this compound increases to approximately 275 g/L. It can also be noted that boric acid is slightly soluble in pyridine and slightly soluble in acetone. The conjugate base of boric acid is the borate anion.

The acidity of boric acid solutions is known to increase with polyols containing cis-vicinal diols such as mannitol and glycerol. The pK of B(OH)3 is known to extend over five orders of magnitude (from 9 to 4) at different concentrations of mannitol. It may be noted that in the presence of mannitol, a boric acid solution with increased acidity may be referred to as mannose boronic acid.
Boric Acid is a weakly acidic boron oxide hydrate with mild antiseptic, antifungal and antiviral properties. The exact mechanism of action of boronic acid is unknown; it is generally cytotoxic to all cells. It is used to treat yeast infections and cold sores.
Boric acid is a member of boric acid. It has astringent effect. It is the conjugate acid of dihydroborate.
Boric acid is an odorless white solid. Melting point 171 °C. Sink and mix with water.
What is boric acid (H3BO3)?
Boronic acid is a monobasic Lewis acid with the chemical formula H3BO3.
It is an acid compound of boron, oxygen and hydrogen. Boric acid is also known as acidum boricum, hydrogen borate, boric acid, and orthoboric acid. It is a weak acid with antiviral, antifungal and antiseptic properties.
