Silicic acid is the general name for a family of chemical compounds containing the element silicon attached to oxide and hydroxyl groups. This family of compounds have the general formula ()n.〔N. N. Greenwood, A. Earnshaw, ''Chemistry of the Elements'', 2nd ed., Butterworth-Heinemann, Oxford, UK, 1997.〕〔R. K. Iler, ''The Chemistry of Silica'', Wiley, New York, 1979.〕 Some simple silicic acids have been identified, but only in very dilute aqueous solution, such as ''metasilicic acid'' (H2SiO3), ''orthosilicic acid'' (H4SiO4, pKa1=9.84, pKa2=13.2 at 25 °C), ''disilicic acid'' (H2Si2O5), and ''pyrosilicic acid'' (H6Si2O7); however in the solid state these probably condense to form polymeric silicic acids of complex structure. == Chemical reactions == In general, silicic acid reactions are difficult to control. Partial dehydration to metasilicic acid, for example, is challenging because the reaction typically progresses all the way to silicon dioxide and water. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Silicic acid」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
