7783-36-0 Usage
Chemical Properties
White, pale yellow or beige powder
Uses
For making electric batteries; with zinc sulfate in the standard Clark cell and with cadmium sulfate in the standard Weston cell.
General Description
White to yellow crystalline powder. Soluble in hot sulfuric acid, dilute nitric acid. Highly toxic.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
MERCUROUS SULFATE is incompatible with the following: Acetylene, ammonia, chlorine dioxide, azides, calcium (amalgam formation), sodium carbide, lithium, rubidium, copper .
Purification Methods
The white-yellow powder is recrystallised from dilute H2SO4., dried in a vacuum under N2, and stored in the dark. Its solubility in H2O is 0.6% at 25o. It is hydrolysed by excessive washing with H2O to form the greenish-yellow basic salt Hg2SO4.Hg2O.H2O.
Check Digit Verification of cas no
The CAS Registry Mumber 7783-36-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7783-36:
(6*7)+(5*7)+(4*8)+(3*3)+(2*3)+(1*6)=130
130 % 10 = 0
So 7783-36-0 is a valid CAS Registry Number.
