Prominent & Leading Manufacturer and Supplier from Vapi, we offer Periodate Chemical such as Potassium Periodate and Sodium Periodate.
CAS No 7790-21-8
Application / Uses Preparation 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. On heating (especially with manganese(IV) oxide as catalyst), it decomposes to form potassium iodate, releasing oxygen gas.
Application / Uses Preparation Sodium periodate is the sodium salt of periodic acid. It can refer to two different chemical compounds, sodium metaperiodate (often abbreviated as m-periodate), which has the formula NaIO4, and sodium orthoperiodate (often abbreviated as o-periodate), which has the formula Na5IO6. Both salts are useful in certain synthetic chemistries for the oxidative power of the periodate ion.
