- Substance
Potassium biiodate appears as a white crystalline powder. It has a molecular weight of 389.91 g/mol and is soluble in water, allowing for easy preparation of solutions for titration. The compound is hygroscopic, meaning it can absorb moisture from the air, which may affect its stability and accuracy in analytical applications. Its melting point is not explicitly stated, but it typically decomposes upon heating, releasing iodine and other products. The density of potassium biiodate is approximately 2.5 g/cm³, indicating its relatively high mass for a salt.
