Preparation
Iron(II) hydroxide may be prepared by precipitation of an iron(II) salt solution with caustic soda or caustic potash in the absence of air. Pure compound may be obtained by mixing solutions of caustic potash and iron(II) sulfate— both the solutions made in freshly boiled water—in a reducing atmosphere of hydrogen: Fe2+ + 2OHˉ → Fe(OH)2.
Structure and conformation
Iron(II) hydroxide crystallizes with the CdI2 layer structure in which every iron atom is
surrounded by six OH groups.
Check Digit Verification of cas no
The CAS Registry Mumber 18624-44-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,6,2 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18624-44:
(7*1)+(6*8)+(5*6)+(4*2)+(3*4)+(2*4)+(1*4)=117
117 % 10 = 7
So 18624-44-7 is a valid CAS Registry Number.
