Diffusion of .Wv into Air Through K0SO4 Solution.—This solutionis the first of the sulphates and is to be compared w4th sodic sulphate andpossibly with the alums. The solution of K2SO4 showed a density of p„ = at 23°, corresponding therefore to 8 grams of K2SO4 in 100 gramsof solution or grams in 100 grams of water. The vapor pressure wastaken as 7r = 7r(i —). The results are given in table 37 and fig. 32 a.
