利用牛顿迭代方法计算给出硼酸钾溶液中硼酸根离子的物种分布图。研究给出溶液中硼酸根离子的类型、含量以及各硼酸根离子间相互转化方程式,并简单谈论了温度和浓度对硼酸根离子类型和含量的影响。在五硼酸钾溶液中主要硼酸根离子物种为B3O3(OH)4-,B4O5(OH)42-和B(OH)3,而B5O6(OH)4-含量非常低,可以忽略不计;偏硼酸钾溶液中主要离子为B(OH)4-;在高浓四硼酸钾溶液中主要物种为B3O3(OH)4-,B4O5(OH)42-和B(OH)4-。最后用Otakar和Casteel-Amis经验方程式分别研究了硼酸钾溶液的密度和电导率。
The Newton iteration method was used to calculate the species distribution of borate ions in potassium borate solution. The type and content of the borate ions in the solution and the equations for the conversion between the respective borate ions are given. The effects of temperature and concentration on the type and content of the borate ions are briefly discussed. The main borate ion species in the potassium pentaborate solution are B3O3 (OH) 4-, B4O5 (OH) 42- and B (OH) 3, while the B5O6 (OH) 4- content is very low and negligible; potassium metaborate The main ions in the solution were B (OH) 4-. The main species in the concentrated potassium tetraborate solution were B3O3 (OH) 4-, B4O5 (OH) 42- and B (OH) 4-. Finally, the density and conductivity of the potassium borate solution were separately studied using Otakar and Casteel-Amis empirical equations.
