Only the
proportionality constant KH differs from p1
0 Thus, Raoult’s law becomes
a special case of Henry’s law in which KH becomes equal to p1
0 Another important class of solutions consists of solids dissolved in
liquid, for example, sodium chloride, glucose, urea and cane sugar in
water and iodine and sulphur dissolved in carbon disulphide Some
physical properties of these solutions are quite different from those of
pure solvents
