Description
CHROMIUM POTASSIUM SULFATE, also known as chrome alum and chrome potash alum, is a crystalline compound with a chemical formula of CrK(SO4)2·12H2O. It exhibits a dark, violet-red color and is efflorescent and soluble in water. The compound is derived by reducing potassium dichromate in dilute sulfuric acid with sulfurous acid. The higher the pH, the more chromium (III) is adsorbed on the surface of potassium sulfate crystal powder, which acts as a crystal growth suppressor.
Uses
Used in Tanning Industry:
CHROMIUM POTASSIUM SULFATE is used as a tanning agent for chrome-tan liquors, providing a durable and water-resistant finish to the tanned hides.
Used in Textile Industry:
CHROMIUM POTASSIUM SULFATE is used as a mordant in the textile dyeing process, enhancing the colorfastness and quality of the dyed fabrics.
Used in Photography Industry:
CHROMIUM POTASSIUM SULFATE is used in the fixing bath of the photographic development process, ensuring the stability and longevity of the developed images.
Used in Ceramics Industry:

Check Digit Verification of cas no
The CAS Registry Mumber 10141-00-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,4 and 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 10141-00:
(7*1)+(6*0)+(5*1)+(4*4)+(3*1)+(2*0)+(1*0)=31
31 % 10 = 1
So 10141-00-1 is a valid CAS Registry Number.
