Which aqueous solution, among those listed, has the highest boiling point?
The aqueous solution with the highest boiling point among those listed is the one with the highest concentration of solute particles.
Which of the aqueous solution has the highest boiling point?
The aqueous solution with the highest boiling point would be the one with the highest concentration of solutes, such as salts, acids, or bases. These solutes increase the boiling point of water by raising the solution's boiling point elevation above that of pure water.
Which one of the following aqueous solutions would have the highest freezing point: a solution of sodium chloride, a solution of glucose, or a solution of ethylene glycol?
A solution of ethylene glycol would have the highest freezing point among the three options.
Explain why the vapor pressure boiling point and freezing point of an aqueous solution if a nonvolatile solute are not the same as those of the pure solvent?
The presence of a nonvolatile solute in an aqueous solution lowers the vapor pressure of the solution, raising its boiling point and lowering its freezing point compared to the pure solvent. This occurs due to the solute molecules occupying space at the surface of the solution, reducing the number of solvent molecules escaping into the vapor phase. As a result, a higher temperature is needed to reach the same vapor pressure as the pure solvent for boiling, and a lower temperature is needed for the solution to freeze.
Which compound has the highest boiling point among the following options?
The compound with the highest boiling point among the options provided.
Which aqueous solution, among those listed, has the highest boiling point?
The aqueous solution with the highest boiling point among those listed is the one with the highest concentration of solute particles.
What are some things that are true about boiling points?
The boiling point of 2 m KF in water is 102.4ºC. The boiling point of a 0.5 m aqueous solution of LiOH is the same as the boiling point of a 0.5 m aqueous solution of LiCl.
Is the boiling point of a 0.5 m aqueous solution of KOH higher than the boiling point of a .5m aqueous solution of KCL?
Colligative properties, such as boiling point elevation, depend on the molality of the solution and the number of "entities" (ions, in this case) per formula unit. For the solutions specified, these are identical, so the answer is no.
What is the boiling point of concentrated aqueous solution of sodium chloride?
The boiling point of a concentrated aqueous solution of sodium chloride is higher than that of pure water. This is due to the presence of the solute, which raises the boiling point of the solution through a process called boiling point elevation. The exact boiling point will depend on the concentration of the sodium chloride in the solution.
What is the boiling point of an aqueous solution that has a vapor pressure of 18.5 at 25 degrees Celsius?
The boiling point of an aqueous solution can be calculated using the formula: ΔT = iKbm, where ΔT is the boiling point elevation, i is the van't Hoff factor, Kb is the ebullioscopic constant, and m is the molality of the solution. Given the vapor pressure of 18.5 mmHg, you can determine the molality of the solution and then calculate the boiling point elevation.
What is the freezing point of an aqueous solution if the boiling point of an aqueous solution is 101.34 degree Celsius?
The freezing point of an aqueous solution will be lower than 0°C (32°F) if the boiling point is elevated above 100°C. The freezing point depression is a colligative property dependent on the concentration of solute particles in the solution. To determine the specific freezing point, more information on the solute and its concentration is required.
Which of the aqueous solution has the highest boiling point?
The aqueous solution with the highest boiling point would be the one with the highest concentration of solutes, such as salts, acids, or bases. These solutes increase the boiling point of water by raising the solution's boiling point elevation above that of pure water.
Which one of the following aqueous solutions would have the highest freezing point: a solution of sodium chloride, a solution of glucose, or a solution of ethylene glycol?
A solution of ethylene glycol would have the highest freezing point among the three options.
Compared to the pure water an aqueous solution of calcium chloride has a?
Higher boiling point and a lower freezing point. These are called colligative properties. When a solute is put into solution with the solvent, there is a change in the vapor pressure, osmotic pressure, elevation of the boiling point, and depression of the freezing point.

How do you separate KNO3 from aqueous sol of KNO3?
You can separate KNO3 from its aqueous solution by a process called evaporation. Simply heat the solution to evaporate the water, leaving behind solid KNO3. This method exploits the fact that KNO3 has a much higher boiling point compared to water.
Is the boiling point of 1 m aqueous lower then the boiling point of 1 m aqueous Pb?
Yes it is using the mathematic formula rise/run=pie2+40
