Iodic acid

Iodic acid is a chemical compound with the formula HIO_3. It is a white crystalline solid and is one of the most important oxides of iodine. Iodic acid is a strong acid and is used in various chemical reactions and industrial processes.

Chemical Properties

Iodic acid is a strong acid with a pKa of 0.75. It is highly soluble in water and ethanol but insoluble in ether. The compound has a monoclinic crystal structure and a dipole moment of 2.13 D. It decomposes upon heating to produce iodine pentoxide (I_2O_5) and water.

Synthesis

Iodic acid can be synthesized by the oxidation of iodine with strong oxidizing agents such as nitric acid or chlorine in the presence of water. The reaction is as follows: <math> I_2 + 5 H_2O + 5 Cl_2 → 2 HIO_3 + 10 HCl </math>

Uses

Iodic acid is used in various applications including:

• As a strong oxidizing agent in chemical reactions.
• In the preparation of iodates, which are used in analytical chemistry.
• In the production of disinfectants and antiseptics.

Safety

Iodic acid is classified as a hazardous substance. It is corrosive and can cause severe burns upon contact with skin or eyes. It is also harmful if ingested or inhaled. Proper safety measures should be taken when handling iodic acid, including the use of personal protective equipment.
