对一项实验过程进行了详细记录,实验的目的是为了深入探究溶液中加入含有相同离子的微溶物时,对溶液溶解度实际产生的影响情况。本次实验还对同离子效应的真实性加以探究和验证。借助平衡方程设计了本次实验,通过测量添加微溶物前后,以及随着微溶物添加量逐渐增加时,溶液PH值的变化,来间接计算出溶解度和平衡常数值,进而验证溶解度的变化。通过实验充分证明了同离子效应的真实性,并且得出一些基本的结论。此外,还以实验数据为基础,对实验的局限性和今后的改进方法进行分析。
An experiment was recorded in detail. The purpose of the experiment was to investigate in depth the influence of the solubility of the solution on the solubility of the solution containing the same ions added to the solution. This experiment also explores and verifies the authenticity of the same ion effect. This experiment was designed with the aid of the equilibrium equation. Solubility and equilibrium constants were calculated indirectly by measuring the changes of the pH value of the solution before and after the addition of the micro-solubles, and as the amount of the micro-solubles added gradually increased to verify the changes of the solubility . The experiment verifies the authenticity of the same ion effect and draws some basic conclusions. In addition, based on the experimental data, the limitations of the experiment and future improvements are analyzed.
