What does thiocyanate do to cyanide?
In small doses, cyanide can be metabolized into thiocyanate with the assistance of the hepatic enzyme, rhodanese. Thiocyanate is then excreted in urine. A small amount of cyanide can also be converted to carbon dioxide which leaves the body through exhalation.
What is ferric thiocyanate method?
The ferric thiocyanate method, previously described for the determination of fat-peroxides in milk powder, has been modified for use in the study of rancidity in fats and oils.
What is thiocyanate used for?
In the early 20th century, thiocyanate was used in the treatment of hypertension, but it is no longer used because of associated toxicity. Sodium nitroprusside, a metabolite of which is thiocyanate, is however still used for the treatment of a hypertensive emergency.
What is the thiocyanate ion?
Thiocyanate is a pseudohalide anion obtained by deprotonation of the thiol group of thiocyanic acid. It has a role as a human metabolite. It is a pseudohalide anion and a sulfur molecular entity. It is a conjugate base of an isothiocyanic acid and a thiocyanic acid.
Is potassium thiocyanate toxic?
Potassium thiocyanate is a skin and eye irritant and is toxic when ingested. Eye contact will cause redness and pain. Skin contact will cause localised irritation. Ingestion will cause headache, nausea, vomiting, dizziness and faintness.
What happens when you add thiocyanate to Fe3+ in determination of total iron in water?
Testing for iron(III) ions with thiocyanate ions If you add thiocyanate ions, SCN-, (e.g., from sodium or potassium or ammonium thiocyanate solution) to a solution containing iron(III) ions, you get an intense blood red solution containing the ion [Fe(SCN)(H2O)5]2+.
What is the formula for iron thiocyanate complex?

|Parent Compound||CID 781 (Thiocyanic acid)|
Is iron thiocyanate toxic?
Handling, Storage, and Precautions: metal thiocyanates on heating to decomposition, or on contact with acid or acid fumes, emit highly toxic fumes.
What is the recommended PPE when handling ammonium thiocyanate?
Eye Protection * For liquified Ammonium Thiocyanate wear indirect-vent, impact and splash resistant goggles. * Wear a face shield along with goggles when working with corrosive, highly irritating or toxic substances.
Is thiocyanate a carcinogen?
The results indicate that sodium thiocyanate is without carcinogenic activity in rats, alone or combined with sodium nitrite.
