Assuming standard pressure (1 atm.) and an ideal solution of a non-volatile solute, the boiling point elevation depends only on the solvent, and on the molality of the solution, not the solute type. For water is a 0.521 deg C increase per mole of solute ions/molecules per kg of water.

What happpens to the boiling point of a solution?
At the boiling point liquids become gases and if the solution contain dissolved solids they remain as residues.
Is alcohol solution boiling point higher or lower than salt solution?
Lower. The boiling point of ethanol is 78 degrees C. Adding salt to water raises the boiling point of that solution above 100 degrees C.
What is the boiling point of glucose dissolved in water?
The boiling point of a solution can vary depending on the concentration of solute. For a dilute solution of glucose in water, the boiling point elevation is typically small and may not be easily measurable. However, pure glucose itself does not have a defined boiling point as it decomposes upon heating.
Which has a higher boiling point 0.50 NaCl or 0.50 MgCl2?
The magnesium chloride solution has a higher boiling point.
What happens to the boiling point of a solution as the concentraion increases?
Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. The boiling point can be measured accurately using an ebullioscope.
The boiling point of a liquid solution is?
Higher then the boiling point of the solvent.
The difference between the boiling point of a liquid in pure state and the boiling point of the liquid in solution?
Boiling Point Elevation
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 a 2.0 molal solution of glucose?
The boiling point is 101 oC.
What happpens to the boiling point of a solution?
At the boiling point liquids become gases and if the solution contain dissolved solids they remain as residues.
What is the boiling point of a liquid solution?
It all depends on the liquid, like waters boiling point is diffent then something like Mercury
Is alcohol solution boiling point higher or lower than salt solution?
Lower. The boiling point of ethanol is 78 degrees C. Adding salt to water raises the boiling point of that solution above 100 degrees C.
What is the boiling point of a 2.47 molal solution of napthalene in benzenethe boiling point of benzene is 80.1?
To determine the boiling-point elevation of the solution, we need to use the formula: ΔTb = iKbm, where ΔTb is the boiling point elevation, i is the van't Hoff factor (for napthalene, i = 1 because it doesn't dissociate), Kb is the ebullioscopic constant of the solvent (benzene), and m is the molality of the solution (2.47 mol/kg). Plug in the values and solve for ΔTb. Add this value to the boiling point of benzene (80.1°C) to find the boiling point of the solution.
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.
What is boiling point of 1 molar urea solution?
The boiling point of a 1 molar urea solution will be higher than the boiling point of pure water. Urea is a non-volatile solute that raises the boiling point of the solution through boiling point elevation. The exact boiling point elevation can be calculated using the formula: ΔTb = i * K_b * m, where i is the van't Hoff factor (1 for urea), K_b is the ebullioscopic constant of the solvent (water), and m is the molality of the solution.
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?
Yes, the boiling point of a 0.5 m aqueous solution of KOH would be higher than the boiling point of a 0.5 m aqueous solution of KCl. This is because KOH is a strong electrolyte that dissociates into more ions in solution compared to KCl, leading to a greater increase in boiling point due to the colligative properties of the solution.
What is the boiling point of glucose dissolved in water?
The boiling point of a solution can vary depending on the concentration of solute. For a dilute solution of glucose in water, the boiling point elevation is typically small and may not be easily measurable. However, pure glucose itself does not have a defined boiling point as it decomposes upon heating.
