Which of the following will have highest freezing point at 1 atm pressure?

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 has highest freezing point 0.1 M urea 0.2 M sucrose?

Sucrose is a non – ionic compound, hence i = 1. Hence, the highest freezing point is 0.1 m of NaCl solution.

What is the freezing point of 1 molar glucose?

-1.86°C.
1M of glucose solution has a freezing point of -1.86°C.

Why is freezing point depression of 0.1 m solution nearly twice that of 0.1 m glucose solution?

Answer: Freezing point depression of 0.1m nacl solution nearly twice that of 0.1m glucose solution because NaCl is a strong electrolyte and it dissociates to give two ions and , whereas glucose is a non electrolyte and it does not dissociate to give ions.

What will be the freezing point depression of 0.4 m NaCl solution and 0.4 m glucose solution?

According to Van’t Hoff, Van’t Hoff factor for\[NaCl\] is 2 and for glucose, it is 1. Van’t Hoff factor is more means freezing point depression is more. So, the freezing point depression (\[\Delta {{T}_{f}}\]) of 0.4 M \[NaCl\] solution is nearly twice that of 0.4 M Glucose solution.

What is the freezing point of 0.1 molar aqueous urea solution?

1 molal urea solution freezes at -1.86°C.

Which 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.

Which of the following solution will have highest freezing point depression?

Answer: Al2(SO4)3 will have higher freezing point depression.

Which of the following will have highest freezing point depression?

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 solution shows less depression in freezing point than urea?

0.1 M urea solution shows less depression in freezing point than 0.1 M MgCl 2 solution. Explain. 0.1 M urea solution shows less depression in freezing point than 0.1 M MgCl 2 solution because MgCl 2 is electrolyte that dissociate to give 3 ions. Hence it has depression in freezing point than urea.

What is the difference between MgCl2 and urea?

0.1 M urea solution shows less depression in freezing point than 0.1 M MgCl2 solution. Explain. 0.1 M urea solution shows less depression in freezing point than 0.1 M MgCl2 solution. Explain. Please log in or register to add a comment.

What is the freezing point depression of 5\% sugar solution?

The freezing point depression of 0.001m K x [ F e ( C N) 6 ​] is 7.10 x 1 0 − 3 K, Determine the value of g x given, ↓ f ​ = 1.86 k kg/mol for water. A 5 \% solution (by mass) of cane sugar in water has freezing point of 2 7 1 K and freezing point of pure water is 2 7 3. 1 5 K.

What is the ratio of depressions in freezing point for NaCl?

The depressions in freezing point for 1 m urea, 1 m glucose and 1 m NaCl are in the ratio: A 1 : 2 : 3 B 3 : 2 : 2
