- n. A salt containing the negative tetravalent radical Fe(CN)6, used in making blue pigments, blueprint paper, and ferricyanide.
Century Dictionary and Cyclopedia
- n. A compound of a base or basic radical with ferrocyanogen. Potassium ferrocyanide, or yellow prussiate of potash, is commercially the most important ferrocyanide, being the starting-point for the production of all the cyanogen compounds. It is prepared by fusing in iron pots potassium carbonate, various sorts of animal refuse, as bone, hair, blood, etc., and iron-filings. The fused mass is digested with water, and the yellow prussiate of potash separated by crystallization. It is a powerful oxidizing agent, and is used in the arts.
- n. chemistry any of various salts containing the tetravalent anion Fe(CN)64-; used in making blue pigments
- n. chemistry a complex ion in which a central ferrous iron atom is surrounded by six cyanide ions
GNU Webster's 1913
- n. (Chem.) One of a series of complex double cyanides of ferrous iron and some other base.
- n. salt of ferrocyanic acid usually obtained by a reaction of a cyanide with iron sulphate
“Add 5 c.c. of a standard zinc solution, equivalent in strength to the standard "ferrocyanide," re-titrate, and finish off cautiously.”
“To standardise the "ferrocyanide" measure off 50 c.c. of the standard zinc solution into a 10 oz. beaker, dilute to 100 c.c., and heat to about 50° C. (not to boiling).”
“Fifty divided by the quantity of "ferrocyanide" solution required gives the standard.”
“It is not necessary to filter off a portion of the assay before testing with the "ferrocyanide," since the precipitate (uranic arsenate) has no effect.”
“ferrocyanide" solution from an ordinary burette, and finish off cautiously.”
“You apply iron chloride on one hand and let it dry and put potassium ferrocyanide on the other hand and let it dry.”
“Many of the preservatives are not required to be listed on the container and include ferrocyanide, magnesium carbonate, and aluminum hydroxide.”
“The toxic parts of oil paints: Vandyke red, ferrocyanide; iodine scarlet, mercuric iodide; flake white, lead carbonate; cobalt violet, arsenic — all those beautiful compounds and pigments that artists treasure but turn out to be deadly.”
“Such is a membrane of copper ferrocyanide which separates sugared water from pure water.”
“To apply the test, strongly acidulate with acetic acid, and then add a few drops of recently prepared potassic ferrocyanide solution.”
