How are the boiling point and freezing point of a solvent affected when a solute is added?

How are the boiling point and freezing point of a solvent affected when a solute is added?

How are the boiling point and freezing point of a solvent affected when a solute is added? The boiling point increases, and the freezing point decreases.

Which one has highest freezing point 1M glucose?

1M glucose solution has the highest freezing point because it has lower ΔTf​(ΔTf​=Tf∘​+ΔTf​) since it does not undergo dissociation to increase the number of particles.

Which has the highest freezing point 1M k4?

So, the value of van’t Hoff factor for NaCl is2. So, the van’t Hoff factor is lowest for C6H12O6 solution so, the 1 m C6H12O6 solution has highest freezing point.

What is the freezing point of pure water?

0 °C

Which of the following has highest depression in freezing point?

urea

Which of the following 0.1 M solution will have higher freezing point depression?

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.

Which of the following solution will have higher freezing point depression and why?

Solution. Al2(SO4)3 solution contains more number of particles than NaCl solution. Hence, Al2(SO4)3 solution has maximum ΔTf. Therefore, the freezing point depression of 0.05 m Al2(SO4)3 solution will be higher than 0.1 m NaCl solution.

Which of the following solutions will have higher freezing point depression and why 1 0.1 m NaCl 2 0.05 m Al2 SO4 3?

Answer: The correct answer is – 0.05 M Al₂(SO₄)₃ has a higher freezing point. Explanation: Al₂(SO₄)₃ dissociates in water to give 5 mol of ions per mole of the compound.

Which of the following 0.01 M aqueous solution will have the largest freezing point?

ΔTf (freezing point depression) is a colligative property and depends upon the van’t Hoff factor (i) i,e., number of ions given by the electrolyte in aqueous solution. Hence, Al2(SO4)3 will exhibit largest freezing point depression due to the highest value of i. 25. D.

Which of the following aqueous solution has maximum boiling point?

Na2St4

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

Explanation: K2SO4 ionises to give three ions as a result of which effective molality in solution increases by three times. Hence, its freezing point is lowest.

Which has highest boiling point?

Tungsten
