| 摘 要： | 讨论金属单质与水溶液体系中酸和碱作用过程的热力学问题．用酸碱溶剂理论探讨金属的酸碱性质，指出金属单质在与酸和碱的反应过程中总是作为碱；两性金属的酸性是由相应的金属离子或其相应的氢氧化物所决定，确定某金属是否具有两性性质，不能根据它是否溶于酸和碱，而应根据其溶解过程中溶液酸碱度的变化．

| 关 键 词： | 两性金属，酸碱反应，热力学，酸碱性质 |

| Abstract: | Thermodynamic characteristics on the reactions of elementary metal withacid and base in aqueous soltltion respectively were discussed and the acid-base character ofmetal was studied by the solvent-system acid-base definition. The elementary metal actedas base in the process of acid-base reaction. The acid character of amphoteric metal resulted from its ions or its hydroxide compotlnd. It is not the dissolvement of metal in alkalineor acid solution but the challge of acidity and basicity in the dissolving process decides thecharacter of amphoteric metal. |
