Table of Contents

What is normal BP of an aqueous solution?

An aqueous solution has a normal boiling point of 103.0 c.

What is the normal BP of an aqueous solution whose freezing point is degree C?

Therefore, boiling point of the solution is 100.7019 °C.

What is the boiling point of an aqueous solution that freezes at OC?

Hence the correct answer is option (D) i.e. an aqueous solution freezes at -2.55 $^{0}C$ the boiling point is 100.7$^{0}C$.

Which of the following is 0.10 aqueous solution?

Hence, 0.10M(≈0.10m) aqueous solution will have the lowest feezing point.

What is the freezing point of an aqueous solution?

Freezing point of an aqueous solution is −0.

What is the boiling point of an aqueous solution?

1, the molal boiling point elevation constant for water is 0.51°C/m. Thus a 1.00 m aqueous solution of a nonvolatile molecular solute such as glucose or sucrose will have an increase in boiling point of 0.51°C, to give a boiling point of 100.51°C at 1.00 atm.

Which of the following aqueous solutions will have the highest depression in freezing point?

So the depression in freezing point is 0.003. So here the lowest depression in freezing point has sucrose, hence it will have the highest freezing point.

Which of the following change will decrease the Vapour pressure of the 0.1 M aqueous solution of Agno _( 3?

The answer would be the option number 2. As it would increase the concentration of the solution. So this way the vapour pressure would decrease. So if you add 0.2 M solution of AgNO3 to 0.1 M AgNO3 then the vapour pressure would decrease.

What is the molal depression constant of water?

The molal depression constant for water is 1.86^oC .

What is the boiling point of 1 molal aqueous 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 solution has highest freezing point?

Hence, the highest freezing point is 0.1 m of NaCl solution.

Which aqueous solution has the highest boiling point?

Solution: 1 M AlC l 3 solution will have the highest boiling point is because colligative properties such as elevation in boiling point is directly proportional to number of particles in solutions and AlC l 3 produces highest number of particles or ions.

Which of the following aqueous solutions has the highest?

As we known greater the value of van’t Hoff factor higher will be the elevation in bonding point and hence higher will be the boiling point of solution. Hence 1.0MNa2SO4 has highest value of bonding point.

What aqueous solution will have the lowest freezing point?

Among the solutions, 0.15 m NaCl has the lowest freezing point.

Which of the following aqueous solution has minimum freezing point?

The aqueous solution of 0.01M NaCl has a minimum freezing point.

What is the freezing point of an aqueous 1.00 m NaCl solution?

(Assume complete dissociation of the salt.) 12. 13. What is the freezing point of an aqueous 1.00 m NaCl solution? (Kf = 1.86 oC/m) (Assume complete dissociation of the salt.).

What is the molality of nicotine in an aqueous solution?

The molality of the nicotine solution is 0.242 m.

What is the freezing point of an aqueous solution of 0.100 m k2so4?

The freezing point of a 0.100 m aqueous solution of K2SO4 is -0.43°C.

How do you find the boiling point of aqueous solution?

The change in temperature for the boiling point of a solution follows the equation ΔTb = Kbmi, where Kb represents the boiling point elevation constant (for water, Kb = +0.52oC/m), m represents the molality of the solution (moles of solute/kg of solvent), and i represents the van’t Hoff factor.

Which aqueous solution has the lowest boiling point?

The solution with the lowest boiling point is 0.50 m LiCl (Choice C).

Why does solute decrease freezing point?

Freezing point depression is the phenomena that describes why adding a solute to a solvent results in the lowering of the freezing point of the solvent. Adding solute to a solvent will essentially dilute the solvent molecules, and according to Raoult’s law, this leads to a decrease in vapor pressure.

Which has high depression in freezing point?

Lowering the freezing point allows the street ice to melt at lower temperatures. The maximum depression of the freezing point is about −18 °C (0 °F), so if the ambient temperature is lower, NaCl will be ineffective. Under these conditions, CaCl2 can be used since it dissolves to make three ions instead of two for NaCl.

Which of the following aqueous Molal solution has highest freezing point?

∴ urea is not ionised hence it is shows highest freezing point.

What will cause by increasing the temperature of an aqueous solution?

An increase in temperature increases the volume of the solution and thus, decreases its molarity.

Which of the following 0.10 M aqueous solution will have the lowest freezing point?

Which of the following 0.10 m aqueous solution will have the lowest freezing point? while KI provides two ions and C5H10O5 and C12H22O11 are not ionised, so they have single particle. Hence, lowest freezing point is possible for Al2(SO4)3.

Which of the following change will increase the vapour pressure of 1 molal aqueous solution?

However, the addition of solvent, ie, dilution increases the surface area of the liquid surface, thus results in increased vapour pressure. Hence, the addition of water to the aqueous solution of (1 molal) KI, result in increased vapour pressure.

Which is a colligative property?

Colligative properties of solutions are properties that depend upon the concentration of solute molecules or ions, but not upon the identity of the solute. Colligative properties include vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure.

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.

What does KB and KF depend on?

The value of Kb or Kf depends only on the type of solvent & not solute dissolved in it.

What is the boiling point of a 2.0 M aqueous solution of sodium chloride?

The new boiling point is 102.0oC.

What is freezing point of a solution?

The freezing point is the temperature at which the liquid solvent and solid solvent are at equilibrium, so that their vapour pressures are equal. When a non-volatile solute is added to a volatile liquid solvent, the solution vapour pressure will be lower than that of the pure solvent.

What is the boiling point of 1 molal aqueous solution of urea?

The boiling point of 0.1 molal aqueous solution of urea is 100.18°C at 1 atm.
