Periodic Acid Formula

Periodic Acid Formula

Periodic Acid was discovered by Heinrich Gustav Magnus and C. F. Ammermuller in the year 1833. Hydrogen, iodine, and oxygen are the elements that make up periodic acids. Hydrogen is the most flammable, colourless, odourless, tasteless, and lightest gas. It has an atomic number of 1, and the letter H is used to denote it. Group 17 of the periodic table contains the non-metallic, solid, lustrous element iodine. It has a dark grey appearance. It has an atomic number of 53, and the letter I is used to denote it. Iodine is the least reactive and most electropositive element in its group. The non-metal oxygen is a highly reactive non-metal that belongs to the group-16 chalcogen. It has an atomic number of 8, and the letter O stands for it. The highest oxoacid of iodine is found in the Periodic Acid Formula, which contains iodine. The element with oxygen, hydrogen, and another element in it is known as an oxoacid.

Since the Periodic Acid Formula is an oxoacid of iodine, the iodine atom has a +7 oxidation state, which means that there are three oxygen atoms double-bonded to the central atom and one hydroxyl group singly bonded to it.

 What is Periodic Acid?

A crystalline compound with no colour, periodic acid is soluble in both alcohol and water. There are two types of periodic acid: ortho periodic acid, which has the chemical formula H5IO6, and meta periodic acid, which has the formula HIO4. As seen in oxidation state VII, it has the highest iodine oxoacid. Any of the different iodine oxides with a higher oxygen content than iodic acid are known as periodic acid. Hydrogen periodate, paraperiodic acid, and iodic (VII) acid are some of the other names for Periodic Acid Formula. To examine the structural characteristics of carbohydrates, periodic acid is used. It is employed to produce acetaldehyde and higher aldehydes by separating ammonia (NH3) from hydroxy amino acids. Periodic Acid Formula is an effective oxidising agent.

 Properties Of Periodic Acid 

Periodic Acid Formula HIO4. Periodic acid has a molecular weight of 191.908 g/mol. Periodic Acid Formula has a melting point of 128.5°C. Periodate is a conjugate base. Alcohol and water are both soluble in Periodic Acid Formula HIO4. Orthoperiodic acid dehydrates into metaperiodic acid when heated. Strong oxidising agents include periodic acid and its salts.

 Periodic Acid Structural Formula

Orthoperiodic acid crystallises as monoclinic crystals (space group P21/n) made up of bridging hydrogens connecting IO6 octahedrons that are slightly deformed. One I-O bond has a distance of 1.78, and five I-O bond distances fall between 1.87 and 1.91.  IO6 octahedra are also present in the structure of metaperiodic acid, but they are joined by cis-edge-sharing and bridging oxygens to form one-dimensional infinite chains. Periodic Acid Formula HIO4, like all periodates, has the ability to cleave a variety of 1,2-difunctional compounds. The Periodic Acid Formula, in particular, will split vicinal diols into two aldehyde or ketone fragments. This can be helpful in figuring out how carbohydrates are structured because saccharide rings can be opened using periodic acid. Using this method, saccharides are frequently labelled with fluorescent molecules or other tags like biotin. Periodate oxidation is frequently used to selectively label the 3′-termini of RNA (ribose has vicinal diols) rather than DNA because deoxyribose does not have vicinal diols because the process requires them. As demonstrated by the Babler oxidation of secondary allyl alcohols into enones by stoichiometric amounts of orthoperiodic acid with the catalyst PCC, periodic acid is also used as a moderately potent oxidising agent.
