Question: Which 0.1 M Solution Has The Highest Boiling Point?

Which has minimum freezing point?

An aqueous solution of urea has freezing point of −0..

What is the freezing point of a 0.1 M solution of glucose?

The freezing point of 0.1 M glucose solution is 1.

Which aqueous solution has minimum depression freezing point?

The freezing point depression of a 0. 1 M aqueous solution of weak acid (HX) is −0.

Which of the following has maximum freezing point?

1 molar of urea solution has maximum freezing point. The depression in the freezing point is a colligative property and depends on the number of solute particles present in the solution.

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.

What liquid has the highest freezing point?

ButaneButane liquifies at -0.5 °C and freezes at -138 °C (it liquifies at higher temperatures when it’s under pressure).

Which is not a Colligative property?

Video Explanation. Colligative properties are the properties which depend upon the number of solute particles present in the solution. Optical activity does not depends upon number of particles present hence it is not a colligative property. Hence, option B is the answer.

Which solution has the highest Vapour pressure?

Answer is C How ?? Dear Student, Vapour pressure depends directly on temperature and inversely on concentration of solute.So, the solution having greater temperature and lesser concentration will have highest vapour pressure and the one having greater concentration and least temperature will have least vapour pressure.

Which solution has the lowest freezing point?

The solution which has the lowest freezing point temperature is 0.

How do you rank up freezing points?

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.

Which has the highest freezing point at 1 atm?

The molar volume of liquid benzene (density=0. 877gmL−1) increases by a factor of 2750 as it vaporises at 20∘C while in equilibrium with liquid benzene. … The freezing point of equimolal aqueous solution will be highest for : 1 Verified Answer. … Calculate the depression in freezing point of water when 20.

Which has lowest boiling point at 1 atm pressure?

HeliumThe 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 Salt raise boiling point?

Adding salt to water actually raises the boiling point of the water, due to a phenomenon called boiling point elevation. Essentially, adding any non-volatile solute (such as salt, baking soda or sugar) to a liquid causes a decrease in the liquid’s vapour pressure.

What is freezing point and boiling point?

FREEZING POINT: The ‘freezing point’ of a substance is the level of temperature at which a ‘liquid’ is converted into ‘solid’. In case of mixtures, the freezing point is comparatively lower than the boiling point. … For example, the ‘freezing point’ of ‘water’ is 0 degree Celsius.

How do you know which aqueous solution has the highest boiling point?

Colligative properties like boiling point elevation, depend on the total number of particles in solution. The solvent used here is water. So elevation in boiling point will be above a boiling point of water for all solutions. Higher ΔT will have a higher boiling point.

Which has higher boiling point 0.1 m nacl or 0.1 M glucose?

The boiling point depends only on the Van’t Hoff factor. That means higher the Van’t Hoff factor, higher will be the boiling point and vice-versa. Hence, 0.1 M of NaCl has the higher boiling point.

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 solution has the lowest boiling point?

The boiling point of 0.1 M urea solution is less than that of 0.1 M KCl solution.

What is the boiling point of 1 molar solution of NaCl?

Pure water – microscopic view. Normal boiling point = 100.0oC. 1.0 M NaCl solution – microscopic view. Normal boiling point = 101.0oC.

Which of the following has more boiling point?

2 – Methyl pentane has the highest boiling point because the boiling point in alkane depends upon the chains of atoms and the molecular mass of the molecules. Straight-chain molecules have higher boiling point than the branched-chain compounds.

Which of the following Aqua solution has maximum freezing point?

The highest freezing point will be of the solution having the lowest ΔTf value. Therefore, 0. 01 M NaCl solution will have the highest freezing point. Hence, the correct option is B.

How do you know which compound has a higher boiling point?

Alkanes just have carbon and hydrogen atoms with no functional groups, so the only intermolecular force that influences the boiling point is London dispersion forces. The more the molecules can touch each other, the more London dispersion forces there are, and the higher the boiling point.

Which solution has highest boiling point?

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. This is maximum number of particles as compared to other solutes.

What affects boiling point?

Atmospheric Pressure and Boiling The pressure of gas above a liquid affects the boiling point. In an open system this is called atmospheric pressure. The greater the pressure, the more energy required for liquids to boil, and the higher the boiling point.
