1303-34-0 Usage
Chemical Properties
ARSENIC PENTASULPHIDE is yellow or orange powder(s); stable in air up to 95°C; can be prepared by fusing As and S or by passing H2S through HCl solution of arsenic acid; used as a paint pigment, in light filters [HAW93] [KIR78]
Physical properties
Yellow-brown glassy amorphous solid; sublimes on heating; decomposes around 500°C; insoluble in cold water (~1.4 mg/L at 0°C); dissolves in alkalies and solutions of alkali metal sulfides, and in nitric acid.
Uses
Different sources of media describe the Uses of 1303-34-0 differently. You can refer to the following data:
1. ARSENIC PENTASULPHIDE is used for preparation of glasses with small gold additions posessing photoluminescent and conductive properties 1 Reactant for preparation of silver thioarsenate complex ethylenediammonium salt 2
2. In thin sheets as a light filter; in pigments.
3. Used for preparation of glasses with small gold additions posessing photoluminescent and conductive propertiesReactant for preparation of silver thioarsenate complex ethylenediammonium salt
Preparation
Arsenic pentasulfide is prepared by precipitation from an acidic solution of orthoarsenic acid, H3AsO4, or arsenic pentachloride, AsCl5 or any other soluble As(V) salt by passing hydrogen sulfide. It may be also prepared by heating a mixture of arsenic and sulfur, extracting the fused mass with ammonia solution and reprecipitating arsenic pentasulfide at low temperature by addition of HCl.
Check Digit Verification of cas no
The CAS Registry Mumber 1303-34-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,0 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1303-34:
(6*1)+(5*3)+(4*0)+(3*3)+(2*3)+(1*4)=40
40 % 10 = 0
So 1303-34-0 is a valid CAS Registry Number.
