16921-30-5 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 16921-30-5 differently. You can refer to the following data:
1. orange to yellow crystalline powder
2. Potassium chloroplatinate, K2 PtCl6, yellow solid, insoluble, formed by reaction of soluble potassium salt solution and chloroplatinic acid.
Uses
Different sources of media describe the Uses of 16921-30-5 differently. You can refer to the following data:
1. Used in the quantitative determination of potassium.
2. Potassium chloroplatinate is a red colored crystal that is
soluble in water but less soluble in alcohol. Potassium chloroplatinate
is produced by a complicated treatment of the
reducing of platinum chloride with sulfurous gas and adding
potassium chloride. It was used primarily in the platinum
printing process, but also for toning silver prints.
General Description
Potassium hexachloroplatinate (K2PtCl6) is a source material for the preparation of platinum based compounds. It can be used in the preparation of platinum colloids by its reduction in an aqueous solution.
Hazard
Toxic by ingestion and inhalation.
Flammability and Explosibility
Notclassified
Safety Profile
Mutation data reported.
Human systemic effects by intradermal
route: dermatitis. When heated to
decomposition it emits toxic fumes of K2O
and Cl-. Used as a catalyst for carbonylation
of alkynes. See also PLATINUM
COMPOUNDS.
Purification Methods
It crystallises from water (20mL/g) between 100o and 0o. Its solubility in H2O is 0.7% at 0o, 1.12% at 20o, 2.16% at 50o and 5.13% at 100o. [Grube in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1571 1965.]
Check Digit Verification of cas no
The CAS Registry Mumber 16921-30-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,2 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16921-30:
(7*1)+(6*6)+(5*9)+(4*2)+(3*1)+(2*3)+(1*0)=105
105 % 10 = 5
So 16921-30-5 is a valid CAS Registry Number.
