Scott, The American Mineralogist, (1971), 56, 355〕 Gallium hydroxide is amphoteric. In strongly acidic conditions, the gallium ion, Ga3+ is formed. In strongly basic conditions, Ga(OH)4− is formed. Salts of Ga(OH)4− are sometimes called gallates.〔 ==References== 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「Gallium(III) hydroxide」の詳細全文を読む スポンサード リンク
