What is iron thiocyanate used for?
Oxidation of ferrous to ferric ion and subsequent complexation of the latter by thiocyanate is known as ferric thiocyanate assay and is used for determination of presence of various oxidizers, such as lipid hydroperoxides, and evaluation of effects of antioxidants.
What is the name of FeSCN2+?
iron(III) thiocyanate complex ion
I. Introduction. This experiment outlines the techniques necessary to determine the equilibrium constant for the formation of an iron(III) thiocyanate complex ion (FeSCN2+) from Fe3+ and SCN- .
How is iron thiocyanate complex ion concentration calculated?
1 Answer
- [Fe3+]=[SCN−]=0.060 M.
- [FeSCN2+]=3.94 M.
What is SCN 2+ called?
Iron(II) Thiocyanate Fe(SCN)2 Molecular Weight — EndMemo.
Why is thiocyanate used in spectroscopy?
The equilibrium constant between iron(III) ion and thiocyanate ion to form a thiocyanatoiron(III) ion can be conveniently measured with visible spectrophotometry because the FeSCN+2 solutions are deep blood-red. Hence this reaction is often used when teaching chemical equilibrium to students of general chemistry.
What is the Colour of iron thiocyanate?
red-colored
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) + +. The last formula is supported by the work of Bent and others [(3)].
How do you calculate iron thiocyanate concentration?

- To find the initial concentration of Fe3+, use the dilution equation: (M1V1)/V2 = M2, where V2 = 10 mL.
What is the initial concentration of SCN?
– To find the initial concentration of SCN–, use the dilution equation: (M1V 1)/V 2 = M2, where V2 = 10 mL. – To find the initial concentration of Fe3+, use the dilution equation: (M1V 1)/V 2 = M2, where V2 = 10 mL.
What is the equilibrium constant for iron (III) thiocyanate?
The well-known colorimetric determination of the equilibrium constant of the iron(III)−thiocyanate complex is simplified by preparing solutions in a cuvette. For the calibration plot, 0.10 mL increments of 0.00100 M KSCN are added to 4.00 mL of 0.200 M Fe(NO 3 ) 3 , and for the equilibrium solutions, 0.50 mL increments of 0.00200 M KSCN are added to 4.00 mL of 0.00200 M Fe(NO 3 ) 3 .
