从物质的式量及其价数确定物质的当量时,由于条件及物质的不同,在实际应用中及书本的理论阐述上,分立了许多计算公式,并对氧化剂和还原剂的当量另立了氧化还原当量名称,以区别于一般物质的化学当量。这样,在应用上固有方便之处,但当量的统一概念及—些计算公式的来历变得不够显明;氧化还原当量和一般物质的化学当量甚至被误解为两个不相同的概念。而有些计算公式过于机械且有局限性,不够灵活普遍,应用时容易造成错误。本文建议把元素或根的化合价的概念推广于一般物质的分子而引用分子价或式量份概念,并确定其涵义及比较准则。这样,对化学当量和氧化还原当量的统一概念可以更
When determining the equivalents of substances from the quantity of substances and their valences, due to the differences in conditions and substances, in practical applications and theoretical explanations of books, many calculation formulae are separated, and the equivalents of oxidants and reducing agents are established separately. The name of the redox equivalent is to be distinguished from the chemical equivalent of the general substance. In this way, the inherent convenience in the application, but the concept of the equivalent and the origin of some calculation formulas become less obvious; the redox equivalents and the chemical equivalents of common substances are even misunderstood as two different concepts. Some calculation formulas are too mechanical and have limitations. They are not flexible and universal, and they are prone to errors when applied. This paper proposes to generalize the concept of valence of elements or roots to molecules of general materials and quote the concept of molecular valences or quantifiers, and determine their meanings and comparison criteria. In this way, the unified concept of chemical equivalents and redox equivalents can be more
