At which temperature does a concentrated aqueous solution of sodium chloride begin to boil?
A concentrated aqueous solution of sodium chloride (table salt) will start to boil at a higher temperature than pure water, due to the colligative properties of the salt. The boiling point elevation for a 1 molal solution of sodium chloride is around 1.88°C.
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.
Would a dilute or concentrated sodium fluoride solution have a higher boiling point?
Concentrated. concentrated solutions is completely ionized. The colligative property that is boiling-point states that it will increase as the number of particles increases. Diluting a concentrated substance lessens the number of particles making it obviously lower in bp
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.
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.

Which aqueous solution has the highest boiling point?
The aqueous solution with the highest boiling point is the one with the highest concentration of solute particles, such as salt or sugar, dissolved in water.
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.
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 has a higher boiling point 0.50 NaCl or 0.50 MgCl2?
The magnesium chloride solution has a higher boiling point.
What are the boiling points of salt and water?
The boiling point of sodium chloride is 1 413 0C.
What is the residue when sodium chloride water solution was heated to dryness?
When a mixture of sodium chloride and water is heated to dryness, the residue is sodium chloride, because the boiling point of sodium chloride is much higher than the boiling point of water.
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.
