Periodic acid is HIO4 or H5IO6. The name is not derived from "period", but from "iodine": per-iodic acid (compare iodic acid, perchloric acid), and it should thus be pronounced per-iodic and not as in the usual meaning of periodic.
In dilute solution, periodic acid exists as H+ and IO4−. When more concentrated, orthoperiodic acid, H5IO6, is formed. This can be obtained as a crystalline solid. Orthoperiodic acid can be dehydrated to metaperiodic acid, HIO4. Further heating gives diiodine pentoxide (I2O5) and oxygen; apparently the anhydride 'diiodine heptoxide' does not exist in nature but can be formed synthetically.
Thus, two forms of periodates exist. One relating to the acid HIO4, the other relating to H5IO6. The former results in metaperiodates (meta- meaning less water) and the latter, orthoperiodates (ortho- meaning more water). Metaperiodates have solubilities and chemical properties similar to perchlorates (similar but larger ion size) though they are less oxidizing than perchlorates.
Periodic acid is also used in organic chemistry for structural analysis. Periodic acid will cleave a vicinal diol into two aldehyde fragments. This can be useful in determining the structure of carbohydrates.

What happens when picric acid reacts with sodium bicarbonate?
When picric acid reacts with sodium bicarbonate, it produces carbon dioxide gas, water, and sodium picrate. The carbon dioxide gas can be observed as bubbling or effervescence during the reaction. Sodium picrate is a less explosive compound compared to picric acid.

How does a complete structural formula differ from a condensed structural formula?
------ The condensed structural formula is simply a shortened version of the complete structural formula. -------The complete formula indicates all of the carbon and hydrogen atoms. The condenced formula groups the hydrogen atoms with each of the carbon atoms.
What is the chemical formula of sulfurous acid?

What is the picricacid formual?
picric acid (or 2,4,6-trinitrophenol) is more acidic than benzoic acid The pKa or picric acid is 0.3 and that of benzoic acid is 4.2
what is picramic acid?
Picramic acid is an organic compound that is derived from picric acid, which is a nitro compound. It has the chemical formula C6H4N2O3 and is formed by the reduction of picric acid. Picramic acid is primarily used in the synthesis of dyes and other organic compounds.
What is IUPAC name of picric acid?
The IUPAC name for picric acid is 2,4,6 trinitrophenol
Which is more acidic hydrochloric acid or picric acid?
Hydrochloric acid is more acidic than picric acid. Hydrochloric acid fully dissociates in solution to release hydrogen ions, resulting in a lower pH compared to picric acid, which is a weaker acid that does not fully dissociate in solution.
What is the mass percent of nitrogen in the dyeing agent picric acid (C6H3N3O7)?
The percentage of nitrogen in the picric acid is 18,34 %.
In real picric acid is not acid..then why it called acid?
Picric acid is acidic, as it has a fairly acidic phenolic proton. However, picric acid is not a carboxylic acid. Nevertheless, it is still called 'acid' because of its acidic proton, just as phenol was once called 'carbolic acid'.
What is the structural formula of oil of vitriol?
Oil of Vitriol is an old name for sulfuric acid (H2SO4). Sulfuric acid's structural formula is:
How picric acid is strong acid?
Picric acid is a strong acid because it readily donates a proton (H+) in solution, making it highly reactive with bases. It has a low pKa value, indicating that it dissociates almost completely in water to release hydrogen ions. This property gives picric acid its characteristic acidic behavior.
Why was picric used in treating burns?
i truelywanna know why was picric acid used to treat burns?
How will you prepare picric acid from benzene?
Picric acid can be prepared from benzene by first nitration to form nitrobenzene, followed by further nitration and subsequent treatment with a nitric/sulfuric acid mixture to yield picric acid. The process involves multiple steps and careful control of reaction conditions to avoid explosive hazards. It is important to handle picric acid with caution due to its potentially explosive nature.
