What reading level is Solutions; Being the Fourth Book, With Some Additions, of the 2d Ed. of Ostwald's Lehrbuch Der Allgemeinen Chemie; book?
To quickly assess the difficulty of the text, read a short excerpt:
In a system of co-or- dinates, the abscissffi of which represent temperatures and the ordinates represent vapour-pressures (fig. 26), let iv be the pressure-curve of water, and e that of ice (which Kirchoff has shown to agree with that of water with a break at 0°), and let I be that of the solution; then the freezing-point of the solution is determined by the abscissa of the point of intersection of e and I. Now, by the law of Babo and Wiillner (p. 157) the proportional decrease of the vapour-p...ressure of the solution, p, compared with that of water, p,^, is expressed by the formula ^° -^^ =ac, where c is the concentration, i.e. the quantity oi' salt divided by the quantity of water, and a is a constant!
Another expression may be found for the magnitudes of the pressures. According to the dynamical theory of heat, the relation between the quantity of heat, r„, required to evaporate unit weight of liquid, which in this case is water, the pressure, and the volume of the saturated vapour, V, is expressed thus : — ' AT dl ' ' where t is the absolute temperature, and — is the me- A chanical equivalent of heat.
