Pure ethylene glycol has a freezing point of −12.9∘C , and water’s freezing point is 0∘C .Click to see full answer. Similarly, what is the freezing point constant of naphthalene?The freezing point for naphthalene is 80.2°C and it Kf = 6.9 °C/m.Additionally, what is the KF of ethylene glycol? List of boiling and freezing information of solvents Solvent Boiling point (°C) Kf (°C/mol/kg) Ethylene glycol 197.3 –3.11 Formic acid 101.0 –2.77 Naphthalene 217.9 –6.80 Nitrobenzene 210.8 –7.00 Also question is, what is the freezing point constant? Kf is the molal freezing point depression constant of the solvent (1.86 °C/m for water). m = molality = moles of solute per kilogram of solvent.What is the freezing point of benzene? 5.5 °C
