Potassium periodate - Citizendia

Potassium periodate has formula KIO₄.

Density is 3,618 kg m^-3. It melts at 581. 85 °C and has a molecular weight of 230. 0 g/mol.

It is slightly soluble in water (one of the less soluble of potassium salts, owing to a large anion), giving rise to a solution that is slightly alkaline. In Chemistry, an alkali (from Arabic: Al-Qaly القلي القالي) is a basic, ionic salt of an Alkali metal On heating (especially with manganese(IV) oxide as catalyst), it decomposes to form potassium iodate, releasing oxygen gas. Manganese(IV oxide is the Chemical compound MnO2 commonly called manganese dioxide.

The low solubility of KIO₄ makes it useful for the determination of potassium.

Note that the pronunciation is per-iodate, not period-ate.
