摘要
建立基于lg(V_(Br-)/V^(2)_(总))=nlg(C_(NH_(3))·V(NH_(3))/V_(总))+lgK′的直线方程进行银氨配离子配位数及稳定常数测定实验,简化了实验操作,有助于学生对实验的理解。改用Excel来处理实验数据和作图找出线性拟合关系,减少了人工处理数据带来的误差,提高了数据处理的速度和准确性。实验结果与文献值接近。
The linear equation based on lg(V_(Br-)/V^(2)_(总))=nlg(C_(NH_(3))·V_(NH_(3))/V_(总))+lgK′was established to determine the coordination number and stability constant of silver ammonia coordination ions,the experimental operation was simplified and the experiment could be understood better by students.Used Excel instead to process experimental data and draw graphs to find out the linear fitting relationship,the using of Excel reduced the error caused by manual data processing and improved the speed and accuracy of data processing.The experimental results were close to the values in the literature.
