Potassium chromate(CAS:7789-00-6)
Potassium chromate is the inorganic compound with the formula (k2cro4). This yellow solid is the potassium salt of the chromate anion. It is a common Laboratory chemical, whereas sodium chromate is important industrially.It is a Class two carcinogen. [applications] Unlike the less expensive sodium salt, potassium salt is mainly used for laboratory work in situations where an anhydrous salt is required. It is as an oxidizing agent in organic synthesis. It is used as in qualitative inorganic analysis, e.G. As a colorimetric test for silver ion. Properties Chemical formula, crk2o4 Molar mass, 194.19 gâ·molâ??1 Appearance, yellow powder Odor, odorless Density, 2.7320 g/cm3 Melting point, 968 â°c Boiling point, 1000 â°c Solubility in water, 62.9 g/100 ml (20 â°c) 75.1 g/100 ml (80 â°c) 79.2 g/100 ml (100 â°c) Solubility, insoluble in alcohol [health risks] As with other chromate compounds, potassium chromate can cause harm to your health if you ingest or inhale this chemical. Potassium chromate is a known carcinogen and can cause cancer. Further, potassium chromate is a poison, and ingesting large amounts of this substance can kill you. In nature, potassium chromate only occurs in a few remote areas of the atacama desert in south america. Additionally, potassium chromate can cause birth defects in the event of fetal exposure to this chemical.
