对25℃下的氯化钍溶液进行了等静压测量。这些结果并没有被认为是非常准确的，但它们是一些有趣的，因为它们增加了我们对1:4和4:1电解质的非常有限的知识，硝酸钍和亚铁氰化钾是仅有的两种已经研究过的电解质。氯化钍是通过对商业样品的结晶制备的，分析表明该样品具有相当的碱性，因此添加的盐酸略多于所需的量，以获得正确的Th: Cl比。溶液经三次再结晶后，经分析得到正确的Th: Cl比。表1给出了以氯化钠作为参比盐的等静力测量结果。表2给出了计算得到的渗透系数和活度系数，后者是在0.05 M时相对于任意值0.350表示的。
Isopiestic vapor pressure measurements have been made on solutions of thorium chloride at 25. The results are not claimed to be of high accuracy but they are of some interest in that they addto our very meager knowledge of 1: 4 and 4: 1 electrolytes, thorium nitrate and potassium ferrocyanide being the only two electrolytes already studied. Thorium chloride was prepared by crystal-lization of a commercial sample which analysis showed to be considerably basic and to which therefore was added slightly more than the requisite amount ofhydrochloric acid to give the correct Th: Cl ratio. After three recrystallizations the solution gave the correct Th: Cl ratio on analysis. Table I gives the results of the isopiestic measure-ments, using sodium chloride as reference salt. Table II gives the calculated osmotic and activity coefficients, the latter being expressed relative to the arbitrary value of 0.350 at 0.05 M.
