Preparation
Magnesium bromide is prepared by treating MgO
with hydrobromic acid and then crystallization
above 0.0°C in solution. The product is the hexahydrate
salt:
MgO+2HBr→MgBr2+H2O→MgBr2·6H2O
The anhydrous form may also be prepared by heating
the hexahydrate with dry HBr gas. This compound can
also be formed directly from the elements:
Mg+Br2→MgBr2
Production Methods
It is also formed by the reaction of magnesium carbonate and hydrobromic acid. The solubility of magnesium bromide is 101 g/ 100 mL of water at 20 °C; the solubility of the hexahydrate is 160 g/ 100 mL of 95% ethanol at 20 °C.
Check Digit Verification of cas no
The CAS Registry Mumber 13446-53-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,4 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 13446-53:
(7*1)+(6*3)+(5*4)+(4*4)+(3*6)+(2*5)+(1*3)=92
92 % 10 = 2
So 13446-53-2 is a valid CAS Registry Number.
