What is the compound formula for silver?
Ag
Silver(I) is Ag+1 and silver(II) is Ag+2. Ionic compounds have to be electrically neutral so the quantity of silver ions in the bond with the sulfate is determined by its charge.
Is SCN a base?
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.
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.

How is thiocyanate produced?
As discussed earlier, thiocyanate is formed from the binding of cyanide and thiosulfate. Thiocyanate is 100-fold less toxic than cyanide and is excreted by the kidney with an approximate elimination half-life of 2.7 days.
Is silver thiocyanate soluble in nitric acid?
Thiocyanate ions, and two of the other anions in this experiment also form precipitates with dilute silver solutions. While addition of nitric acid makes two of these compounds soluble, both silver chloride and silver thiocyanate are insoluble in strong acid.
What type of ligand is thiocyanate?
In most crystal structures the thiocyanate ligand is linear and the bond angle N—C—S diverges only slightly from 180° (e.g. in [Co (py)2(—NCS—)4Hg] [19] two symmetrically independent thiocyanate ligands have bonding angles 179.0° and 178.8°).
What is the molecular geometry of silver thiocyanate?
Each SCN − group has an almost linear molecular geometry, with bond angle 179.6 (5)°. Weak Ag—Ag interactions of length 0.3249 (2) nm to 0.3338 (2) nm are present in the structure. Silver thiocyanate is produced by the reaction between silver nitrate and potassium thiocyanate .
How do you make Silver thiocyanate?
Silver thiocyanate is produced by the reaction between silver nitrate and potassium thiocyanate . ^ a b c dComey, Arthur Messinger; Hahn, Dorothy A. (February 1921).
What is the structure of thiocyanic acid?
Thiocyanic acid is a hydracid that is cyanic acid in which the oxygen is replaced by a sulfur atom. It has a role as an Escherichia coli metabolite. It is a hydracid, a one- carbon compound and an organosulfur compound. It is a conjugate acid of a thiocyanate. It is a tautomer of an isothiocyanic acid.
What is the meaning of thiocyanate?
Thiocyanate. 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.
