What is the chemical formula for ammonium thiocyanate?
Thiocyanate (also known as rhodanide) is the anion [SCN]−.
Why is it called thiocyanate?
Thiocyanate was formerly known as rhodanide (from a Greek word for rose) because of the red colour of its complexes with iron. Thiocyanate is produced by the reaction of elemental sulfur or thiosulfate with cyanide: 8 CN− + S8 → 8 SCN. CN− + S2O32– → SCN− + SO.

Thiocyanate was formerly known as rhodanide (from a Greek word for rose) because of the red colour of its complexes with iron. Thiocyanate is produced by the reaction of elemental sulfur or thiosulfate with cyanide: 8 CN− + S8 → 8 SCN. CN− + S2O32– → SCN− + SO.
Where is thiocyanate found?
Thiocyanate is one of the breakdown products of glycosinolates and cyanide. Glycosinolates are thioglycosides found in cruciferous vegetables of the Brassica family, including cabbage, bamboo shoots, kale, sprout, broccoli, brussel sprouts, turnips, and mustard.

What is the Colour of SCN?
It has an equilibrium constant, K, given by: 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.
Which type of ligand is SCN?
SCN– is an example of an ambidentate ligand. This is because it can bond to a coordination centre through nitrogen as well as sulphur.
What is the oxidation state of SCN?
Since it is a single negative ion, the sum of oxidation number of sulfur, carbon, and nitrogen will be equal to -1. So, the oxidation number of carbon in $SC{{N}^{-}}$ will be +4.
What is arsenate and arsenite?
Chemical Contaminants
Arsenic exists in two oxidation states—arsenate, As(III), and arsenite, As(V)—both of which are anions (see also Chapter 8). Although both forms are toxic, arsenite is much more toxic and is also very soluble and mobile in water environments.
What does arsenate mean?
Definition of arsenate
: a salt or ester of an arsenic acid.
What is the meaning of thiocyanate?
Definition of thiocyanate
: 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.

Is silver thiocyanate a precipitate?
Initially, the thiocyanate reacts with the remaining silver ions to form a precipitate of silver thiocyanate. Once all the silver ions have reacted, the thiocyanate ions start to react with the iron III ions in the mixture to form the characteristic red colour. This is the end point of the titration.
