This isomerism occurs when salts or complex salts with the same chemical formula release different ions when they ionize in solution. There are many examples of this in complex salts. There are two types of complex salts with the chemical formula CoClSO 4・5NH 3 : reddish purple pentaamminechloridocobalt(III) sulfate and rose-colored pentaamminesulfatocobalt(III) chloride. They each ionize in aqueous solution as follows: [CoCl( NH3 ) 5 ] SO4 [Iwamoto Shinbu] [Reference] | |Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
組成式が同じ塩あるいは錯塩が、溶液中で電離した際に異なるイオンを放出する異性現象。錯塩においての例が多い。組成式がCoClSO4・5NH3となる錯塩には、赤紫色のペンタアンミンクロリドコバルト(Ⅲ)硫酸塩とバラ色のペンタアンミンスルファトコバルト(Ⅲ)塩化物の2種類があり、それぞれ水溶液中で次のように電離する。 [CoCl(NH3)5]SO4 [岩本振武] [参照項目] | |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
