Freezing constant of fecl3
Webwhere m is the molal concentration of the solute and K f is called the freezing point depression constant (or cryoscopic constant). Just as for boiling point elevation constants, these are characteristic properties whose values depend on the chemical identity of the solvent. Values of K f for several solvents are listed in Table 11.2. WebQuestion. a) Calculate the freezing point of a solution containing 13.2 g FeCl3 in 156 g water. b) Calculate the boiling point of the solution above. Transcribed Image Text: Calculate the freezing point and boiling point in each solution, assuming complete dissociation of the solute. Use Kf = 1.86 °C/m and K = 0.512 °C/m.
