| Abstract: | The solubility of n-hexanoic acid and n-heptanoic acid at 25℃ was determined respectively in water as well as in the aqueous salt solution. The activity coefficient of the undissociated part of the weak acid fu has also been calculated,When we ploted log fu vs. Cs for eight salts, the results obtained are all straight-lines. |
