Periodic acid is used in organic chemistry for structural analysis.

Limescale may foul the system over time and require periodic acid cleaning.

Periodic acid is found as a colorless solution.

It reacts with acids to make periodic acid.

They are the salts of periodic acid.

Place the face downwards in l% periodic acid (by weight) in distilled water.

Periodate is the conjugate base of periodic acid.

Sodium periodate is the sodium salt of periodic acid.

Periodic acid is not as stable as iodic acid.

Periodic acid (pronounced as per io' dic acid) is a chemical compound.

Periodic acid will cleave vicinal diols into two aldehyde or ketone fragments.

By contrast, the modern structure of (meta) periodic acid has all four oxygen atoms surrounding the iodine in a tetrahedral geometry.

There being two forms of periodic acid, it follows that two types of periodate salts are formed.

Special stains, such as periodic acid schiff and Gömöri methenamine silver, can be used to demonstrate the fungal organisms if needed.

The presence of this carbohydrate can be detected by a periodic acid - Schiff (PAS) reaction.

By histochemistry, the paraganglioma cells are argyrophilic, periodic acid Schiff negative, mucicarmine negative, and argentaffin negative.

A strong to explosive reaction also takes place in combination with halogen compounds, metal nitrides, metal perchlorates, sodium hydride, periodic acid and fluorinating agents.

Sections of Barrett's mucosa were also stained to show neutral and acid mucous substances by the Alcian blue/distance periodic acid Schiff method.

Duodenal biopsy specimens were stained with periodic acid Schiff (PAS) for the detection of metaplastic gastric epithelium.

Other methods of ethylene oxide detection are color reactions with pyridine derivatives and hydrolysis of ethylene glycol with periodic acid.

Silver proteinate (brand name: Protargol) is used in electron microscopy with periodic acid and thiocarbohydrazide or thiosemicarbohydrazide as a positive stain for carbohydrates such as glycogen.

In dilute aqueous solution, periodic acid exists as discrete hydronium (HO) and meta periodate (IO) ions.

The sections (4 m) were stained with haematoxylin and eosin, Alcian blue (pH 2.5)- periodic acid Schiff, and Grimelius techniques.

Paraffin embedded sections were stained for conventional study with haematoxylin-eosin-safran (HES) and periodic acid Schiff (PAS).

Commonly used histologic stains such as mucicarmine or diastase-sensitive Periodic Acid Schiff can be important in confirming the diagnosis of certain tumors of gastrointestinal or renal origin.
