Arrhenius Acid-Base Theory阿伦尼乌斯酸碱理论
The Arrhenius acid-base concept classifies a substance as an acid if it produces hydrogen ions H(+) or hydronium ions in water. A substance is classified as a base if it produces hydroxide ions OH(-) in water. This way of defining acids and bases works well for aqueous solutions, but acid and base properties are observed in other settings. Other ways of classifying substances as acids or bases are the Bronsted-Lowry concept and the Lewis concept. 阿伦尼乌斯酸碱理论将物质定义为酸，如果它在水中能产生氢离子H⁺或水合氢离子。若物质在水中能产生氢氧根离子OH⁻，则被定义为碱。这种定义酸和碱的方法在水溶液中效果良好，但酸碱性质在其他环境中也能被观察到。其他定义物质为酸或碱的方法有布伦斯特-劳里理论和莱施理论。

Bronsted-Lowry Acid-Base Concept布朗斯特-劳里酸碱概念
The Bronsted-Lowry theory classifies a substance as an acid if it acts as a proton donor, and as a base if it acts as a proton acceptor. Other ways of classifying substances as acids or bases are the Arrhenius concept and the Lewis concept. 布伦斯泰德-劳里理论将一种物质定义为酸，如果它能作为质子供体；定义为碱，如果它能作为质子受体。物质的酸碱分类还有其他方法，如阿伦尼乌斯概念和路易斯概念。

Lewis Acid-Base Concept路易斯酸碱概念
The Lewis theory classifies a substance as an acid if it acts as an electron-pair acceptor and as a base if it acts as an electron-pair donor. Other ways of classifying substances as acids or bases are the Arrhenius concept and the Bronsted-Lowry concept. 路易斯理论将物质定义为酸，如果它能作为电子对受体起作用；将物质定义为碱，如果它能作为电子对供体起作用。其他将物质分类为酸或碱的方法还有阿伦尼乌斯概念和布伦斯蒂-劳里概念。
