The material with the lowest freezing point is helium. A freezing point for helium only exists under at least 25 atmospheres of pressure and a temperature of 1.15 K. These conditions have been created in a laboratory through evaporative cooling.Which aqueous solution has the lowest freezing point? 0.35 m NaCl. 0.50 m glucose. Which of the following solutes would be the most soluble at 60°C in 100 g of water? Na3PO4. KNO3.Urea and glucose do not dissociate in solution. Sodium chloride gives two ions and potassium sulphate gives three ions per formula unit. Therefore, the effective number of particles is maximum in potassium sulphate, and it shows the maximum depression in freezing point.The more particles (ions or molecules) that you can put into solution, the lower the freezing point. so the 2.0 Molar NaCl will deliver 2 moles of Na+ and 2 moles of Cl- ions, the highest available concentration is the list of choices.

0.1mCaI2 will have the lowest freezing point, followed by 0.1mNaCl, and the highest of the three solutions will be 0.1mC6H12O6, but all three of them will have a lower freezing point than pure water.which solution has highest freezing point if all are at the same molality calcium chloride sodium nitrate potassium sulfate iron(III) nitrate all have same freezing point please explain how you figure this out. Which aqueous solution will have the lowest freezing point temperature?The freezing-point depression prevents radiators from freezing in winter. Road salting takes advantage of this effect to lower the freezing point of Freezing-point depression is used by some organisms that live in extreme cold. Such creatures have evolved means through which they can...You can lower the freezing point of some liquids by mixing a second, soluble substance into them; this is how road salt keeps melt-water from refreezing in By mixing one liquid with another compatible substance, you lower the freezing point of the liquid. The substances must be compatible to ensure...
Which of the following 0.1 M aqueous solutions will have the low
Solutions from volatile substances have a higher boiling point and lower freezing points than the solvent. Kf = molal freezing point constant. Because of the value of i (a Van't Hoff factor), this electrolyte solution produces a freezing point that is greater than the non-electrolyte solution.The freezing point of a solution is less than the freezing point of the pure solvent. This means that a solution must be cooled to a lower temperature than the pure solvent in order for Note that the molal freezing point depression constant, Kf, has a specific value depending on the identity of the solvent.We have solutions for your book! Step-by-step solution: 100%(60 ratings). for this solution.Freezing point of a pure solvent depends on the amount of solute that gets dissolved in it. In order to determine which solution has the lowest freezing point, we need to look at the molality as well as whether the solute is ionic or covalent. Since the molality is equal for all of the answer choices...Bc KI has a lower freezing point than water. this means that the higher ratio of KI to water you have, the lower the freezing point will be. since 3 Find an answer to your question ✅ "Which solution has the lowest freezing point" in Chemistry if you're in doubt about the correctness of the answers...
Colligative properties: Freezing point despair.
The depression in freezing point is determined by the total quantity of debris present, and the molality of the ones debris. We are given the molarity (now not molality) of the different solutions so we'd really need the density of these solutions to compute molality. But assuming the values won't range an excessive amount of from molarity, we're going to proceed as follows:
a. 0.10 M lithium chloride: 2 debris x 0.1 = 0.2
b. 0.15 M barium nitrate: Three debris x 0.15 = 0.45
c. 0.20 M potassium iodide: 2 debris x 0.2 = 0.4
d. 0.25 M sodium nitrate: 2 debris x 0.25 = 0.5
e. 0.20 M calcium bromide: 3 debris x 0.20 = 0.60 which is the very best value so it would have the biggest effect on the freezing point.
