What temperature does 50/50 antifreeze freeze at?
BOILING & FREEZING POINTS Pure water, as you may know, has a boiling point of 212°F (100°C) and a freezing point of 32°F (0°C). However, when you create a 50/50 mixture using water and ethylene glycol, the boiling point rises to 223°F (106°C) and the freezing point lowers to -35°F (-37°C).
Who is the minimum freezing point?
Solution : 0.01 molal NaCl solution have minimum freezing point because its molality is more and it given two ions after dissociation of one molecule.
Which has the minimum freezing point Mcq?
So, 1 molal CaCl2 solution will shows minimum freezing point.
What is the effect of impurities on freezing point of solvent Mcq?
The presence of impurities lowers the vapour pressure of the solution since the concentration of the solution is increased. So ice melts easily at a lower temperature.
Which has the maximum 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 aqueous solution has maximum freezing point?
We can see that lowest depression in freezing point is of 0.005M C2H5OH as it has least effective particle concentration. Since it has least depression, it has maximum freezing point. ◾️So, the correct answer is option (b).
Which has the 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.
What is the freezing point of 1M glucose?
-1.86∘C .
Which has the highest freezing point 1 M glucose 1’m NaCl?
In the above formula ‘Kfxm’ value is same for both glucose and NaCl. Thus the deprssion in freezing point is more for NaCl. Hence 1M glucose has higher freezing point.
What is the freezing point of glucose?
146 °C
What is the freezing point of alcl3?
192.4 °C
What is the freezing point of 1% solution of glucose in water?
The freezing point of glucose solution =0−2. 48=−2. 48oC.
When glucose is dissolved in water the freezing point will?
Sugar lowers the freezing point of water, which makes frozen desserts fair game for changes in freezing point. Most desserts freeze between 29.5 to 26.6 degrees F (-1.4 to -3.0 C) depending on the concentration of sugar.
What is the freezing point of cacl2?
772 °C
What is the freezing point depression constant of glucose?
The freezing point of a glucose solution ( C6H12O6;molar mass= 180.0 g/mole) is – 10.3 degree C ….
What is the unit of freezing point depression constant?
Kf is the molal freezing point depression constant of the solvent (1.86 °C/m for water). m = molality = moles of solute per kilogram of solvent.
What is the freezing point of na2so4?
884 °C
What is the freezing point of nh4cl?
338 °C
