What is normal BP of an aqueous solution?
An aqueous solution has a normal boiling point of 103.0 c.
What is the normal boiling point of Aqua solution whose freezing point is degree Celsius?
52 K kg mol−1. – So, by applying the formula of elevation in the boiling point we will get the value of elevation in the boiling point in the solution i.e. – So, the elevation in the boiling point of the solution is 0.052∘C. Therefore, option D is the correct answer.
What is the freezing point of an aqueous solution?
Freezing point of an aqueous solution is −0.
Which of the following is 0.10 aqueous solution?
Hence, 0.10M(≈0.10m) aqueous solution will have the lowest feezing point.
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.
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.
How do you find the boiling point of an 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.
What is the freezing point of an aqueous solution of a nonvolatile solute that has a?
freezing point is 0.00 °C.

(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.).
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 aqueous solutions have the lowest freezing point?
The aqueous solution with the lowest freezing point is 1 m MgBr2 , which is choice c.
What is k3po4 freezing point?

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.
What is K2SO4 freezing point?
1,956°F (1,069°C).
Which has largest freezing point?
The lowest van’t hoff factor will result in the least depression in freezing point and hence that solution will have the highest freezing point. Hence, the correct option is D, glucose.
Which has the minimum freezing point?
van’t Hoff factor, i = 2 for NaCl, so concentration = 0.02, which is maximum in the present case. Hence, ΔTf is maximum or freezing point is minimum in 0.01 m NaCl. The aqueous solution of 0.01M NaCl has a minimum freezing point.
Which of the following aqueous solution is the highest boiling point?
Answer: (b) As we know greater the value of van’t Hoff factor higher will be the elevation in boiling point and hence higher will be the boiling point of solution. Hence, 1.0 M Na2St4 has highest value of boiling point.
Which solution has highest freezing?
Hence, the highest freezing point is 0.1 m of NaCl solution.
Which of the following aqueous solutions has the highest freezing point at 1 atm?
As \[FeC{l_3}\] solution comprises the maximum number of solute particles, its freezing point will be the lowest and sugar solution comprises the minimum number of solute particles so its freezing point will be the highest. So, the correct answer is Option B.
Which of the following 01 M aqueous solutions is likely to have the highest depression in freezing point?
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 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.
What solution has the lowest freezing point?
Remember, the greater the concentration of particles, the lower the freezing point will be. 0.1mCaI2 will have the lowest freezing point, followed by 0.1mNaCl, and the highest of the three solutions will be 0.1mC6H12O6, but all three of them will have a lower freezing point than pure water.
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.
Why is freezing point depression a Colligative property?
The freezing point depression thus is called a colligative property. The explanation for the freezing point depression is then simply that as solvent molecules leave the liquid and join the solid, they leave behind a smaller volume of liquid in which the solute particles can roam.
How do you find the freezing point and 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 find the normal boiling point of a solution?
The rather simple equation for determining boiling point of a solution: delta T = mKb. Delta T refers to the boiling-point elevation, or how much greater the solution’s boiling point is than that of the pure solvent. The units are degrees Celsius. Kb is the molal boiling-point elevation constant.
Which Equimolal concentrated solution has highest freezing point?
The freezing point of equimolal soution will be highest for : B. Ca(No3)2. C. La(NO3)3. La(NO3)3will furnish four ions and thus will develop more lowering in freezing point where as glucose gives only one particle and thus lowering in freezing point is minimum.
Which are the Colligative properties?
Colligative properties include vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure.
What is Colligative property class 12?
Colligative properties are properties of a solution which depend only on the number of particles like ions or molecules of the solute in a definite amount of the solvent but not on the nature of the solute. These are as follows: Relative lowering of vapour pressure.
