…A salt of molybdic acid represented by the general formula x M I 2 O・ y MoO 3 ・ z H 2 O. The simplest composition is orthomolybdate M I 2 MoO 4. Molybdic acid has a strong tendency to condense. For example, an aqueous solution of potassium salt K 2 MoO 4 is alkaline, but when acid is added to it, condensation proceeds due to the hydrogen ion concentration, producing isopolymolybdate ions such as Mo 2 O 7 2− , Mo 7 O 24 6− , HMoO 24 5− , Mo 8 O 26 4− , and H 2 Mo 8 O 26 2−. … *Some of the terminology that refers to "orthomolybdate" is listed below.

…一般式xMI2O・yMoO3・zH2Oで表されるモリブデン酸の塩。最も簡単な組成のものはオルトモリブデン酸塩MI2MoO4である。モリブデン酸は縮合する傾向が強く,たとえばカリウム塩K2MoO4の水溶液はアルカリ性を呈するが,これに酸を加えていくと水素イオン濃度により縮合が進み,Mo2O72-やMo7O246-,HMoO245-,Mo8O264-,H2Mo8O262-などのイソポリモリブデン酸イオンを生成する。… ※「オルトモリブデン酸塩」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
