Preparation
The red hygroscopic hexahydrate Cu(NO3)2.6H2O crystallizes from aqueous solutions of cobalt bases in dilute nitric acid at room temperature. It becomes the trihydrate when heated at 56° ; at higher temperatures decomposition occurs.
Purification Methods
Crystallise the nitrate from water (1mL/g), or ethanol (1mL/g), by partial evaporation. After 3 crystallisations from H2O it contains: metal (ppm) As (8), Fe (1.2), K (1), Mg (4), Mn (4), Mo (4), Na (0.6), Ni (18), Zn (1.6). The hexahydrate gives the pink anhydrous salt by the action of HNO3 and N2O5. The hexahydrate melts at ~55o to give a red liquid which decomposes on further heating at 100-105o to form Co3O4.
Check Digit Verification of cas no
The CAS Registry Mumber 10026-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,2 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 10026-22:
(7*1)+(6*0)+(5*0)+(4*2)+(3*6)+(2*2)+(1*2)=39
39 % 10 = 9
So 10026-22-9 is a valid CAS Registry Number.
