**Chemical Formula:** Na₂CrO₄
**Sodium Chromate** is a yellow, crystalline inorganic compound primarily used as an oxidizing agent, corrosion inhibitor, and laboratory reagent. It is highly soluble in water and serves as a key intermediate in the production of other chromium compounds. Due to its strong oxidizing and corrosive properties, it must be handled with care and is typically used in controlled industrial and research environments.
**Appearance:**
Bright yellow crystalline powder
**Uses:**
**Industrial Applications:**
Employed as a corrosion inhibitor in boiler systems, petroleum refining, and cooling towers. Also used in metal treatment and electroplating baths for its passivation properties.
**Chemical Manufacturing:**
Used in the production of chromium-based pigments, catalysts, and other specialty chemicals. Acts as a reagent in oxidation reactions and chrome tanning processes.
**Laboratory & Analytical Use:**
Serves as an oxidizing agent in analytical chemistry and research, particularly in redox titrations and sample digestions.
**Textile Industry:**
Applied in dyeing and printing processes for its ability to stabilize certain dye formulations and enhance fabric binding.
