Cyanosilver salt - Cyanoginsanen

Japanese: シアノ銀酸塩 - シアノギンサンエン
Cyanosilver salt - Cyanoginsanen
A general term for complex salts in which silver ions are coordinated with cyanide ions. When silver cyanide (AgCN) is dissolved in excess of sodium cyanide (NaCN) or potassium cyanide (KCN), [Ag(OH)(CN)] - , [Ag(CN) 2 ] - , [Ag(CN) 3 ] 2- , and possibly [Ag( CN ) 4 ] 3- are produced in the solution. When such a solution of cyanoargentate ions is used for silver plating, a dense surface with good electrodeposition can be obtained. One example of the composition of a silver plating solution is a solution of 30 g of AgCN, 45 g of KCN, and 25 g of potassium carbonate (K 2 CO 3 ) dissolved in 1 liter of water.

銀イオンにシアン化物イオンが配位した錯塩の総称。シアン化銀AgCNを過剰のシアン化ナトリウムNaCNまたはシアン化カリウムKCNに溶解すると[Ag(OH)(CN)],[Ag(CN)2],[Ag(CN)3]2-,またCNの濃度が高い場合にはおそらく[Ag(CN)4]3-も溶液中に生成する。銀めっきにこのようなシアノ銀酸イオンの溶液を用いると,電着性のよい,緻密(ちみつ)な表面が得られる。銀めっき液の組成の一例に,水1lに,AgCN30g,KCN45g,炭酸カリウムK2CO325gを溶かした溶液がある。
