Glycerol has a relatively high boiling point compared to many other organic compounds due to its strong hydrogen bonding and larger molecular size. When in solution, the boiling point can be influenced by the concentration of glycerol and the presence of other solutes. Generally, a pure glycerol solution will have a higher boiling point than many simple solvents, but the exact boiling point of a glycerol solution will depend on its concentration and the identity of any other components present.

Why glycerol decomposes at its boiling point?
Glycerol decomposes at its boiling point due to thermal decomposition, where high temperatures cause the glycerol molecules to break apart into smaller compounds like acrolein and water. This process results in the degradation of glycerol with the release of gases and can lead to discoloration and alteration of its physical properties.
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 is the boiling point of a solution of 72.4 grams of glycerol dissolved in 122.5 grams of water?
First find the molality--convert the 72.4 grams into mols; convert the grams of water into kilograms. Divide the mols by the Kg, which gives you 6.419m.No need to find the mol ions since it's a molecular compound.The molar boiling point constant for water is 0.51.Therefore:Tb=0.51(6.419)Tb=3.27since this is the boiling point elevation and we're trying to discover the new boiling point, add this number to 100 (the average boiling point of water)the final answer is 103.27o c
What is the differences in the boiling point of ethanol and glycerol?
this is because glycerol have two hydroxyl group which form it more boiling pointdue to hydrogen bond while ethanol have one hydroxyl group that is why toform it less boiling boint than glyceerol.
Why glycerol decomposes at its boiling point?
Glycerol decomposes at its boiling point due to thermal decomposition, where high temperatures cause the glycerol molecules to break apart into smaller compounds like acrolein and water. This process results in the degradation of glycerol with the release of gases and can lead to discoloration and alteration of its physical properties.
The boiling point of a liquid solution is?
Higher then the boiling point of the solvent.
Why is the boiling point of glycerol higher than that of 1-pentanol?
Glycerol has a notoriously "bendy" structure with a lot of areas for other glycerol molecules to hook onto it and get tangled in the solution (this is why glycerol is one of the most viscous organic liquids as well) making it harder for the molecules to escape into the gas phase. Ethylene Glycol has a higher bp than ethanol because it has two free oxygen molecules on which hydrogen bonding can occur, while ethanol only has one. Generally you want to look at the type of intermolecular forces that would be present in a solution, the frequency of which they can occur, the mass of the substance (heavier has higher bp), and then the overarching structure of the molecule. Hope this helps!
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.
How can one determine the boiling point of a solution?
The boiling point of a solution can be determined by measuring the temperature at which the solution changes from a liquid to a gas. This temperature is typically higher than the boiling point of the pure solvent due to the presence of solute particles 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.
How can one determine the boiling point elevation of a solution?
The boiling point elevation of a solution can be determined by using the formula: Tb i Kf m, where Tb is the boiling point elevation, i is the van't Hoff factor, Kf is the cryoscopic constant, and m is the molality of the solution. By plugging in the values for these variables, one can calculate the boiling point elevation of the solution.
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
