Abstract The osmotic pressure of NaCl solutions was determined by the air humidity in equilibrium (AHE) method. The relationship between the osmotic pressure and the concentration was explored theoretically, and the osmotic pressure was calculated according to the nonelectrolyte Wilson nonrandom factor (N-Wilson-NRF) model from the concentration. The results indicate that the calculated osmotic pressure is comparable to the measured one.
摘要 通过平衡空气湿度(AHE)法测定了氯化钠溶液的渗透压。从理论上探讨了渗透压与浓度之间的关系,并根据非电解质威尔逊非随机因子(N-Wilson-NRF)模型由浓度计算渗透压。结果表明,计算得到的渗透压与测量值相当。
