Dipotassium chromate (K2CrO4)

Description:

Dipotassium chromate (K2CrO4) is an inorganic compound characterized by its bright yellow color and is commonly used as a chemical reagent and in various industrial applications. It is a potassium salt of chromic acid and is highly soluble in water, forming a yellow solution. The compound exhibits strong oxidizing properties, making it useful in analytical chemistry and as a dye in the textile industry. Dipotassium chromate is also employed in the production of pigments and in the tanning of leather. However, it is important to note that it contains hexavalent chromium, which is toxic and poses environmental and health risks, leading to strict regulations regarding its use and disposal. The compound has a relatively high melting point and is stable under normal conditions, but it can decompose at elevated temperatures, releasing toxic chromium oxides. Safety precautions are essential when handling dipotassium chromate, including the use of personal protective equipment to avoid inhalation or skin contact.
