如何用摩尔理解和表述当量定律,现谈一点认识。一、由摩尔的定义可知,摩尔这个计量单位适用于任何基本单元,如原予、分子、离子、电子及其它粒子或这些粒子的特定组合。例如 1摩尔H_2SO_4,1摩尔1/2H_2SO_41摩尔1/5KMnO_4,1摩尔1/2Hg_2~(2+),1摩尔2CH_3 COOH等等。这里必须注意,基本单元不同的实质和含义。例如1摩尔H_2SO_4和2摩尔1/2H_2SO_4,由于基本单元不同,所表示的含义自然也是不同的。
How to use Moore to understand and express the law of equivalents and talk about a little understanding. First, by the definition of Moore, the molar unit of measurement can be applied to any basic unit, such as original, molecular, ion, electron and other particles or a specific combination of these particles. For example, one mole of H 2 SO 4 , 1 mole 1/2H 2 SO 41 mole 1/5KMnO 4 , 1 mole 1/2Hg 2 2+ , 1 mole 2CH 3 COOH and the like. It must be noted here that the basic unit differs in substance and meaning. For example, one mole of H_2SO_4 and two moles of 1/2H_2SO_4, due to the difference in basic units, naturally mean different things.
