# Quick Answer: How Do You Know Which Solution Has The Highest Boiling Point?

## Which one will have higher boiling point 0.1 M sucrose or 0.1 M KCl solution?

0.1 molal solution of KCl have a higher boiling point because KCl is an ionic compound..

## How do you tell which solution will have the highest boiling point?

Multiply the original molality (m) of the solution by the number of particles formed when the solution dissolves. This will give you the total concentration of particles dissolved. Compare these values. The higher total concentration will result in a higher boiling point and a lower freezing point.

## How do you know which molecule has the highest boiling point?

The stronger the intermolecular force, the higher the boiling point. In general, hydrogen bonding is stronger than dipole-dipole attractions, which are stronger than London dispersion forces.

## Which has maximum boiling point at one atmospheric pressure?

The barium chloride will separate into the most ions at the given concentration. Because the change in boiling point is directly proportional to the number of ions in solution, the barium chloride solution will have the highest boiling point. EDIT: I just realized, I should explain molality as well to be 100% sure.

## Which has the lowest boiling point at one atmospheric pressure?

The boiling point of a liquid at 1 atm is also known as the normal boiling point. It has been found that Helium has the lowest normal boiling point (−268.9 °C) because it has very weak intermolecular attractions.

## Does branching increase boiling point?

Branching decreases the boiling point As the length of carbon chain increases, the surface area of the compound will also increase. Van der Waals dispersion force is proportional to the surface area. So the increase of surface area increases the ability of individual molecules to attract each other.

## Which is not a Colligative property?

Both solutions have the same freezing point, boiling point, vapor pressure, and osmotic pressure because those colligative properties of a solution only depend on the number of dissolved particles. … Other non-colligative properties include viscosity, surface tension, and solubility.

## Which solution will show maximum elevation in B PT?

The solution for which more value of van’t Hoff factor will show maximum elevation in b.pt.

## Which has higher boiling point 0.1 m nacl or 0.1 m bacl2?

Bacl2 will have higher boiling point as boiling point is a colligative property . And the van’t hoff factor of nacl is more than bacl2. Consequently, 0.1M bacl2 will have higher boiling point than 0.1M nacl.

## Which has the highest freezing point?

(a) 1M glucose solution has highest freezing point because it has lowest ΔTf.

## Why does a solution have a higher boiling point?

The boiling point of a solution, then, will be greater than the boiling point of the pure solvent because the solution (which has a lower vapor pressure) will need to be heated to a higher temperature in order for the vapor pressure to become equal to the external pressure (i.e., the boiling point).

## What has the lowest boiling point?

HeliumThe chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten.

## Which solution will have the highest boiling point?

0.1 M MgCl2. B .0.1 M HClO4. C .0.1 M KCl. D .0.1 M KOH. E .0.1 M LiNO3. MEDIUM. Share. Save. Answer. 0.1 M MgCl2 solution has the highest boiling point. Elevation in the boiling point is a colligative property and depends on the number of solute particles. 1 mole of MgCl2 on dissociation in water gives 3 moles of ions.

## What has higher boiling point alcohol or amine?

Amines generally have lower boiling points than alcohols of comparable molar mass because amines have weaker hydrogen bonds than alcohols. Consider the compounds methanol and methylamine. Methanol has strong hydrogen bonds. The strong intermolecular forces give methanol a high boiling point.

## Which of the following 0.1 M aqueous solution will have the lowest freezing point?

Solution : 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.

## What affects boiling point?

The boiling point of a liquid depends on temperature, atmospheric pressure, and the vapor pressure of the liquid. When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling will begin.

## Which of the following 0.1 M solution will show maximum boiling point?

Maximum number of particles (i.e. ions) will be obtained when Cr2(SO4)3 is dissolved in water hence, 0.1 M solution of chromium sulphate will show maximum elevation in boiling point.

## What causes boiling point elevation?

Boiling Point Elevation. A solvent’s vapor pressure will lower when a solute is added. This happens because of the displacement of solvent molecules by the solute. … For the vapor pressure to equal the atmospheric pressure, a higher temperature is required, and a higher boiling point is observed.

## Which of the following will show maximum elevation in boiling point?

Which solution will show maximum elevation in boiling point? Solution : Fe2(SO4)3 furnishes more number of ions.
