| Description | Statistical Study of Distribution Diagrams for Two-Component Systems was studied. The distribution of mononuclear M species is the set of distributions of molar fractions of M species with stoichiometric coefficient of L. The set of means of these distributions corresponds to the average ligant number and that the set of variances of the same distributions is related to the intrinsic buffer capacity of the system. Mean and variance are parameters of a statistical distribution. Then it is possible to show that average ligand number and buffer capacity result from means and variances of the set of distributions of molar fractions, respectively. This viewpoint provides an excellent application example of statistical distributions of a discrete variable and it may be halpful for mathematical statistics courses provided in chemistry teaching programs. |
