WebExample 12.6.1: The Freezing Point of a Solution of an Electrolyte. The concentration of ions in seawater is approximately the same as that in a solution containing 4.2 g of NaCl NaCl dissolved in 125 g of water. Assume that each of the ions in the NaCl NaCl solution has the same effect on the freezing point of water as a nonelectrolyte ... WebFeb 1, 2024 · The freezing points of mixtures of different liquids, or of liquids with solids dissolved in them, change in accordance with the properties of the constituents in a similarly predictable way. Water has a … WebFeb 14, 2024 · Explanation: Where ΔT f = the freezing-point depression. ΔT f = T f (pure solvent) − T f (solution). Kf = the cryoscopic constant, which is dependent on the properties of the solvent, not the solute. m = molality of the solution. Answer link. butter chicken woolworths
