What does thiocyanate mean in chemistry?
: a compound that consists of the chemical group SCN bonded by the sulfur atom to a group or an atom other than a hydrogen atom.
What is the name for Fe SCN 3?
Iron(III) Thiocyanate Fe(SCN)3 Molecular Weight — EndMemo.
What Colour is SCN?
The FeSCN2+ complex that is formed as a result of reaction between iron(III) and thiocyanate ions has a very intense blood red color (or orange in dilute solution), allowing for easy detection and quantitative determination by spectrophotometry. Reactants ( Fe3+ and SCN-) are practically colorless.
What color does FeSCN2+ absorb?
The FeSCN2+ ion produces solutions with a red color. Because the red solutions absorb blue light very well, the blue LED setting on the Colorimeter is used. The Colorimeter measures the amount of blue light absorbed by the colored solutions (absorbance, A).

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 color is thiocyanate?
red-
statements regarding iron (III) thiocyanate: The red-colored compound has been given various formulas, Fe(CNS)6—, Fe(CNS)3, Fe(CNS)2+, and Fe(CNS) + +.
What is the Colour of SCN?
What is the meaning of thiocyanate in chemistry?
Thiocyanate. Thiocyanate (also known as rhodanide) is the anion [SCN] −. It is the conjugate base of thiocyanic acid. Common derivatives include the colourless salts potassium thiocyanate and sodium thiocyanate. Organic compounds containing the functional group SCN are also called thiocyanates.
What are the side effects of thiocyanate?
In areas of low iodine intake, thiocyanate exposure increases the risk of dvelopmental and other iodine deficiency disorders. As the overall effect of thiocyanate is to hamper utilization of iodide, the main effect of thiocyanate is to worsen iodine deficiency.
What is the formula for copper(I) thiocyanate?
Copper (I) thiocyanate. Copper(I) thiocyanate (or cuprous thiocyanate) is a coordination polymer with formula CuSCN. It is an air-stable, white solid used as a precursor for the preparation of other thiocyanate salts.
Is thiocyanate a pseudohalog of OCN?
Thiocyanate. Thiocyanate is analogous to the cyanate ion, [OCN]-, wherein oxygen is replaced by sulfur. [SCN]- is one of the pseudohalogens, due to the similarity of its reactions to that of halide ions. Thiocyanate was formerly known as rhodanide (from a Greek word for rose) because of the red color of its complexes with iron.
