It is the product of the half-neutralization of hydrogen sulfide with potassium hydroxide. The compound is used in the synthesis of some organosulfur compounds.〔Dittmer, D. C. "Potassium Hydrogen Sulfide" in Encyclopedia of Reagents for Organic Synthesis (Ed: L. Paquette) 2004, J. Wiley & Sons, New York. .〕 It is prepared by neutralizing aqueous KOH with H2S.〔Kurzer, F. Lawson, A. "Thiobenzoylthioglycolic Acid" Organic Syntheses, Collected Volume 5, p.1046 (1973). ()〕 Aqueous solutions of potassium sulfide consist of a mixture of potassium hydrosulfide and potassium hydroxide. The structure of the potassium hydrosulfide resembles that for potassium chloride. Their structure is however complicated by the non-spherical symmetry of the SH− anions, but these tumble rapidly in the solid high temperatures. Addition of sulfur gives dipotassium pentasulfide. ==Synthesis== Potassium hydrosulfide is synthesized by the reaction between a solution of potassium sulfide with excess hydrogen sulfide. 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「Potassium hydrosulfide」の詳細全文を読む スポンサード リンク
