The experimentally measured freezing point of a 1.50 m aqueous solution of CaCl2 is -6.70°C. The freezing point depression constant for water is Kf = 1.86°C/m. Assume the freezing point of pure water is 0.00°C. The experimentally measured freezing point of a 1.50 m aqueous solution of CaCl2 is -6.70°C. The freezing point depression constant for water is Kf = 1.86°C/m. Assume the freezing point of pure water is 0.00°C. What is the predicted freezing point if there were no...
Which aqueous solution will have the lowest freezing point? (a) 0.050 m CaCl2 (b) 0.15 m NaCl (c) 0.10 m HCl (d) 0.050 m CH3COOH (e) 0.20 m C12H22O11
What is the freezing point of an aqueous 1.00 m NaCl solution? (Kf = 1.86 *C/m) (Assume complete dissociation of the salt.) I know the answer is -3.78*C but I cannot figure out how to get it. I keep getting -1.86*C. Please show step by step so I can understand. Thank you.
