以Microsoft.NET Framework为开发平台,使用面向对象的C#语言,开发pH计算及滴定曲线绘制的软件。该软件利用分布系数计算各种形态的平衡浓度,根据酸碱质子理论归纳出通用方程后,利用二分法求解氢离子浓度计算pH。软件收集了常见酸碱的离解常数,用户只要输入浓度后就可精算pH值、绘制酸碱滴定曲线,同时提供Excel数据输出、图像保存等功能。如果需要考虑活度,可根据德拜-休克尔公式计算活度系数,使用浓度常数代替活度常数,使所得pH更接近体系真实值。软件计算结果准确、界面友好、容易操作,可广泛应用于各种体系。
With Microsoft.NET Framework as the development platform, the object-oriented C # language is used to develop the software of pH calculation and titration curve drawing. The software uses the distribution coefficient to calculate the equilibrium concentration of various forms. According to the theory of acid-base proton, general equations are generalized, and the pH is calculated by dichotomy for hydrogen ion concentration. The software collects the common acid-base dissociation constants. The user can fine-tune the pH value after inputting the concentration, draw the acid-base titration curve, and provide the functions of Excel data output and image preservation. If activity needs to be considered, the activity coefficient can be calculated from the Debye-Hicker formula and the concentration constant can be used instead of the activity constant to bring the resulting pH closer to the true value of the system. Software calculation accuracy, friendly interface, easy to operate, can be widely used in various systems.
