Periodic Acid Formula: Chemical Structure, Properties

In the Periodic Acid Formula, iodine is in oxidation state VII, the highest oxoacid of iodine. Iodine is found in oxidation state VII of periodic acid, which has the highest oxoacid concentration. Periodic acid is a colorless crystalline compound. Periodic acid is a periodate, meaning it can exist in two forms: orthoperiodic acid, whose chemical formula is H5IO6, and metaperiodic acid, whose chemical formula is HIO4. Water and alcohol dissolve periodic acids.

Periodic Acid Formula

How do you write the formula of periodic acid?

• First of all, we will explain the chemical compound periodic acid. Periodic acid contains iodine, which is the highest oxoacid of iodine. Oxoacids consist of oxygen, hydrogen, and another element.
• Since the periodic acid is an oxoacid of iodine, iodine has a +7 atomic number .Having an oxidation state means that there are three oxygen atoms double bonded to the central iodine atom and one hydroxyl group single bonded to it.

Applications of Periodic Acid

• It is used extensively in organic chemistry as a potent oxidizing agent. Periodic acid has diverse applications both in science and industry. In a reaction called the Malaprade reaction or oxidative glycol cleavage, it is used to cleave vicinal diols, for instance.
• The Periodic Acid-Schiff (PAS) staining technique is particularly valuable in histology and pathology for staining polysaccharides, glycoproteins, and glycolipids.

Periodic Acid: Overview

• It is a pale yellow solution of hydrogen iodide gas. Iodides are iodine compounds with oxidation state -1, such as hydrogen iodide (HI), sodium iodide (NaI), carbon tetraiodide (CI4), and nitrogen triiodide (NI3).
• Hydrogen iodate, HIO3, can be made by oxidizing I2 in an aqueous solution with chlorine. Iodine, an iodate salt of iodic acid, has three oxygen atoms bound to it.
• The prefix "meta" denotes less water, whereas"ortho" denotes more water. Heating can dehydrate orthoperiodic acid to metaperiodic acid. Periodic acid is a white crystal soluble in water and alcohol and loses water at temperatures above 100 degrees Celsius.
• Periodic acid and its salts (potassium and sodium) have powerful oxidizing properties in organic synthesis.
• As the most iodine-rich oxoacid, periodic acid can be used to analyze the structure of carbohydrates. Periodic acid has the chemical formula is HIO4, and meta-periodic acid has the formula HIO4.
• As with all periodates, orthopedic acid has the chemical formula HIO4. In 1833, Heinrich Gustav Magnus and C.F. Ammermüller discovered periodic acid.
