NaCrO

NaCrO, also known as sodium chromate, is an inorganic compound with the chemical formula Na2CrO4. It is a yellow crystalline solid that is highly soluble in water. Sodium chromate is primarily used as a mordant in dyeing and printing processes, as well as a corrosion inhibitor in cooling water systems. It is also used in the manufacture of pigments, glass, and ceramics.

The compound is prepared by the reaction of chromium trioxide with sodium hydroxide. It is a strong oxidizing agent and can cause skin and eye irritation. Prolonged exposure to sodium chromate can lead to chromium poisoning, which can cause damage to the liver, kidneys, and nervous system. Due to its toxicity, the use of sodium chromate is regulated in many countries.

Sodium chromate is classified as a hazardous substance and should be handled with care. It should be stored in a cool, dry place away from incompatible substances such as acids and reducing agents. In case of accidental ingestion, seek medical attention immediately. Proper disposal methods should be followed to prevent environmental contamination.
