一、引言将苯甲酸加到互不相溶的苯和水的体系內,苯甲酸就以一定的浓度比分配在水和苯之間,实驗早就指出,苯甲酸在苯內以双分子締合形式存在,在水內以单分子形式存在,但是在苯层內双分子締合的苯甲酸有部分解离成单分子形式,在水层內苯甲酸有部分解离成氫离子H~+和苯甲酸根离子C_6H_5COO~-,因而当浓度很稀时,由于二者解离度的增大,使得不考虑有
I. INTRODUCTION Benzoic acid is added to the system of benzene and water which are incompatible with each other. Benzoic acid is distributed between water and benzene at a certain concentration ratio. Experiments have long pointed out that benzoic acid is bimolecular in benzene Co-exist, exist in water as a single molecule, but in the benzene layer bimolecular association of benzoic acid partially dissociated into a single molecule form, in the water layer of benzoic acid partially dissociated into hydrogen ions H ~ + And benzoate ions C_6H_5COO ~ -, so when the concentration is very thin, due to the increase of the two dissociation, making irreducible
