就是一种化学当量。【一、化学当量】品 名:当量 英文名称：equivalent说明: 表示元素或化合物相互作用的质量比的数值。元素的当量，是该元素与8个质量单位的氧或1.008个质量单位的氢相化合（或从化合物中置换出这些质量单位的氧或氢）的质量单位（用旧原子量）。例如40.08个质量单位的钙和16个质量单位的氧化合而成56.08个质量单位的氧化钙，在氧化钙中，钙的当量是40.08×8/16=20.04。按照物质的类型不同，它们的当量可以按照下列公式求出：元素或单质的当量=元素的相对原子质量/元素的化合价。例如：钙的当量=40.08/2=20.04。元素的当量往往称化合量(combining weight)。酸的当量=酸的相对分子质量/酸分子中所含可被置换的氢原子数。例如：硫酸H2SO4的当量=98.08/2=49.04。碱的当量=碱的相对分子质量/碱分子中所含的氢氧基数。例如：氢氧化钠NaOH的当量=40.01/1=40.01。盐的当量=盐的相对分子质量/盐分子中的金属原子数×金属的化合价。例如：硫酸铝Al2（SO4）3当量=342.14/2×3=342.14/6=57.03。氧化剂的当量=氧化剂的相对分子质量/氧化剂分子在反应中得到的电子数。例如：高锰酸钾在酸性溶液中（得到5个电子）的当量=158.03/5=31.61。还原剂的当量=还原剂的相对分子质量/还原剂分子在反应中失去的电子数。例如：亚硫酸钠（失去2个电子）的当量=126.05/2=63.03。有关的氧化剂和还原剂的当量，往往总称为氧化还原当量(redox equivalent)。一种物质在不同的反应中，可以有不同的当量。例如铁在2价铁化合物中的当量是55.847/2=27.93，在3价铁化合牧中的当量是55.847/3=18.62。又如铬酸钾K2CrO4作为氧化剂时，当量是194.20/3=64.73；但作为盐时，当量是194.20/2=97.10。物质相互作用时的质量，同它们的当量成正比。知道了物质的当量，可以算出它们在反应中的质量比值。当量浓度(N) 溶液的浓度用1升溶液中所含溶质的克当量数来表示的叫当量浓度，用符号N表示。 例如，1升浓盐酸中含12.0克当量的盐酸(HCl)，则浓度为12.0N。 当量浓度=溶质的克当量数/溶液体积（升） mol/L叫摩尔浓度,即溶液的浓度用1升溶液中所含溶质的摩尔数来表示. 例如1升浓硫酸中含18.4摩尔的硫酸，则浓度为18.4mol。 摩尔浓度（mol）=溶质摩尔数/溶液体积（升） 浓度单位的换算公式： 1）当量浓度=1000.d.质量百分浓度/E 2）质量百分浓度=当量浓度E/1000.d 3）摩尔浓度=1000.d质量百分浓度/M 4）质量百分浓度=质量-体积浓度（毫克/升）/104.d 5）质量-体积浓度（mg/L）=104质量百分浓度 5、ppm是重量的百分率，ppm=mg/kg=mg/L 即:1ppm=1ppm=1000ug/L 1ppb=1ug/L=0.001mg 式中：E—溶质的克当量； d—溶液的比重； M—溶质的摩尔质量；
