base在这句话中应该怎么翻译(急)？ 从反应机理来看，这里base应该是碱的意思。 顺便讨论一下base和alkali 我一般碱都用alkali，后来发现有老外用base，看看alkali和base有什么区别： 金山词霸： base：any of a large class of compounds, including the hydroxides and oxides of metals, having a bitter taste, a slippery solution, the ability to turn litmus blue, and the ability to react with acids to form salts. alkali： a carbonate or hydroxide of an alkali metal, the aqueous solution of which is bitter, slippery, caustic, and characteristically basic in reactions. any of various soluble mineral salts found in natural water and arid soils. alkali metal. from wiki: confusion between alkali and base the terms "base" and "alkali" are often used interchangeably, particularly outside of a scientific context, but they do not have the same meaning. while all alkaline solutions are basic, not all bases are alkaline. the following are common mistakes: the phrase "measuring the alkalinity of soil" is incorrect since the property measured is actually the ph (base property). calling bases that are not alkalis, such as ammonia , alkaline (ammonia is a base but not an alkali). also, not all salts formed by alkali metals are alkaline; this designation applies only to those salts that are basic. and while most electropositive metal oxides are basic, only the soluble alkali metal and alkaline earth metal oxides can be correctly called alkalis. this definition of an alkali as a basic salt of an alkali metal or alkaline earth metal is the most common, based on dictionary definitions [1] [2] , however conflicting definitions of the term alkali do exist. these include: any base that is water-soluble and [3] [4] in chemistry, this is more accurately called an arrhenius base . the solution of a base in water [5] . this would be an arrhenius base in solution. http:///wiki/alkali 这么看来base是碱的总称，alkali是base的一种，指碱金属或碱土金属的氢氧化物或碳酸盐。 [ ]查看更多
