10421-48-4 Usage
Uses
Different sources of media describe the Uses of 10421-48-4 differently. You can refer to the following data:
1. Iron(III) nitrate is used as a mordant for dyeing black and buff. Other applications are in tanning; weighting silks; and in preparation of analytical standards, as a fertilizer and food additive.
2. Dyeing (mordant for buffs and blacks), tanning,
analytical chemistry.
Preparation
Iron(III) nitrate is prepared by the action of nitric acid on iron filings or iron oxide followed by crystallization:
2Fe + 6HNO3 → 2Fe(NO3)3 + 3H2
Fe2O3 + 6HNO3 → 2Fe(NO3)3 + 3H2O
Chemical Properties
Different sources of media describe the Chemical Properties of 10421-48-4 differently. You can refer to the following data:
1. Ferric nitrate is a pale violet, green, or
grayish-white, odorless solid in lumpy crystals (like salt).
2. Violet crystals. Soluble in water and alcohol.
Physical properties
The nonahydrate form occurs as grayish-violet crystal; density 1.68 g/cm3; hygroscopic; decomposes at 47°C; very soluble in water, alcohol and acetone.
General Description
A violet crystalline solid. Noncombustible but Ferric nitrate will accelerate the burning of combustible materials. If large quantities are involved in the fire or the combustible material is finely divided an explosion may result. Prolonged exposure of the material to fire or heat may result in an explosion. Toxic oxides of nitrogen are produced in fires involving Ferric nitrate. Ferric nitrate is used for dyeing and tanning, in chemical analysis, and in medicine.It is a strong oxidant and irritant,and a fire hazard when in contact with organic substances.
Air & Water Reactions
Soluble in water.
Reactivity Profile
Ferric nitrate is an oxidizing agent. Mixtures with alkyl esters may explode, owing to the formation of alkyl nitrates. Mixtures with phosphorus, tin(II) chloride or other reducing agents may react explosively [Bretherick, 1979 p. 108-109].
Hazard
Dangerous fire risk in contact with organic
materials. Strong oxidant and irritant.
Safety Profile
Mutation data reported.A reactive oxidizer.
Potential Exposure
Ferric nitrate is used in textile dyeing,
tanning, and weighting silk.
Shipping
UN1466 Ferric nitrate, Hazard Class: 5.1;
Labels: 5.1-Oxidizer.
Incompatibilities
An oxidizer. Keep away from reducing
agents, oxidizable materials and combustibles including
metal powders, sulfur, and organic materials, combustibles,and easily oxidizable materials. Light sensitive. Aqueous
solution is corrosive to metals.
Check Digit Verification of cas no
The CAS Registry Mumber 10421-48-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,4,2 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 10421-48:
(7*1)+(6*0)+(5*4)+(4*2)+(3*1)+(2*4)+(1*8)=54
54 % 10 = 4
So 10421-48-4 is a valid CAS Registry Number.
