A solution of glucose in water has a freezing point that is?
A solution of glucose in water has a freezing point that is lower than that of pure water due to the presence of solute particles, which disrupt the formation of ice. This phenomenon is known as freezing point depression. The extent of the freezing point depression depends on the concentration of glucose in the solution, as more solute particles lead to a greater decrease in the freezing point.
Which has a lower freezing temperature 0.10 m NaCl or 0.10m glucose?
0.10m NaCl has a lower freezing temperature compared to 0.10m glucose. This is because NaCl dissociates into more particles in solution, causing greater osmotic pressure that lowers the freezing point more than glucose, which does not dissociate.
What is the freezing and boiling point to glucose?
Melting (freezing) point: α-D-glucose: 146 °C β-D-glucose: 150 °C Glucose will decompose already below its boiling point, so there's no valued boiling point (at least not at normal pressure).
What is the change in the boiling point and freezing point of 500 grams of water if 45 grams of glucose C6H12O6 were dissolved in it?
This quantity is equivalent to 90 g glucose / kg water = 0.50 mole particles of solute / kg water, so with a 'molar cryoscopic constant' for water of -1.86 oC/kgthis lowers the freezing point to -0.93 oC.
What would cause the greatest drop in a substance's freezing point... A. Barium Chloride B. Glucose C. Lithium Fluoride?
I suppose that barium chloride cause the greatest drop of the freezing point.
Which one of the following aqueous solutions would have the highest freezing point: a solution of sodium chloride, a solution of glucose, or a solution of ethylene glycol?
A solution of ethylene glycol would have the highest freezing point among the three options.
What is the molal elevation constant of glucose?
The molal elevation constant (Kf) for glucose is typically around 1.86 °C kg/mol. This value is used in the calculation of the freezing point depression when glucose is dissolved in a solvent, such as water. It reflects the change in the freezing point of the solvent per mole of solute particles in a kilogram of solvent. However, since glucose does not dissociate in solution, the effective concentration for calculations remains based on its molality as a non-electrolyte.
What is the antonym for boiling point?
Freezing point.
Which solution containing 1 mole of solute dissolved in 1000 grams of water has the lowest freezing point- KOH C2H5OHC6H12O6C12H22O11?
The solution with glucose (C6H12O6) would have the lowest freezing point. This is because the number of particles in the solution contributes to the lowering of the freezing point, and glucose, being a covalent compound, dissociates into more particles in solution compared to the other compounds given.
