It is commonly found in various forms, such as potassium dichromate and sodium dichromate, and is known for its bright orange color. Dichromate compounds are often used in laboratories and industries for applications like dyeing, tanning leather, and as oxidizing agents in chemical reactions. Dichromate is also recognized for its toxicity and potential environmental hazards. When dissolved in water, it can release harmful chromium ions, which pose risks to human health and ecosystems. Due to these dangers, the use of dichromate is regulated in many countries, and safety precautions are essential when handling it in any form.
