Đầu tiên, cho kim loại crom cháy trong oxi tạo thành crom (III) oxit.
Hòa tan crom (III) oxit trong môi trường natri hidroxit tạo thành natri cromat màu vàng.
Sau đó, cho natri cromat tác dụng với luồng khí CO2 và H2O tạo thành crom (III) hidroxit kết tủa lục xám.
Sau đó, hòa tan crom (III) hidroxit trong môi trường natri hidroxit thu được muối natri cromat.
Cuối cùng cho natri cromat phản ứng với axit HCl thu được crom (III) clorua.
