Question
Which of the following will have a greater boiling point elevation?
Select one:
- a. vinegar solution
- b. ethanol
- c. sugar solution
- d. glucose solution
Solution
The boiling point elevation depends on the number of solute particles in a solution. This is described by the colligative property known as boiling point elevation, which states that the boiling point of a solution is higher than that of the pure solvent.
The more solute particles, the higher the boiling point. Therefore, solutions with larger amounts of solute will have a higher boiling point elevation.
a. Vinegar solution: Vinegar is a solution of acetic acid in water. It is about 5-20% acetic acid by volume.
b. Ethanol: Ethanol is a pure substance, not a solution. Therefore, it does not have a boiling point elevation.
c. Sugar solution: The amount of sugar that can be dissolved in water is quite high. A sugar solution could potentially have a high boiling point elevation if a large amount of sugar is dissolved.
d. Glucose solution: Glucose is a type of sugar. A glucose solution would have a similar boiling point elevation to a sugar solution, assuming the same amount of solute is dissolved.
Without knowing the exact concentrations of the vinegar, sugar, and glucose solutions, it's impossible to say definitively which will have the greatest boiling point elevation. However, if we assume that the solutions are saturated (meaning they contain the maximum amount of solute that can be dissolved), the sugar and glucose solutions would likely have the greatest boiling point elevations because sugar and glucose can be dissolved in water in larger amounts than acetic acid (the solute in vinegar).
