The molal elevation constant is the elevation in boiling point of

Detailed Solution for Test: Concentration of Solutions, Vapour pressure - Question 1

The correct answer is Option B.
 
Molal elevation constant is a characteristic constant for a given solvent. It is the elevation of boiling point produced when one mole of solute is dissolved in 1 kg of solvent. The proportionality constant, Kb, is called the molal boiling point elevation constant. It is a constant that is equal to the change in the boiling point for a 1-molal solution of a nonvolatile molecular solute.

Which of the following modes of expressing concentration is independent of temperature?

Detailed Solution for Test: Concentration of Solutions, Vapour pressure - Question 2
The molality involves weights of the solute and the solvent. Since weight does not change with the temperature, therefore molality does not depend upon the temperature.

Which of the following is not an ideal solution?
Detailed Solution for Test: Concentration of Solutions, Vapour pressure - Question 7
An ideal solution obey Raoult’s law at all temperature and pressures.
The solute-solute and solvent-solvent interactions are similar to solute-solvent interactions.
1. Benzene + Toluene Ideal solution
2. Chlorobenzene -dichlorobenzene Ideal solution
3. Methyl iodide + Isopropanol Non-ideal solution
4. Ethyl bromide + Methyl bromide Ideal solution
Hence, only methyl iodide and isopropanol is not an ideal solution.

An azeotropic solution of two liquids has boiling point lower than either of them when it
Detailed Solution for Test: Concentration of Solutions, Vapour pressure - Question 8
In case of positive deviation from Raoult's law, the observed vapour pressure is greater than the ideal vapour pressure and boiling point of azeotrope becomes lower than either of pure liquid.

A solution of acetone in ethanol
Detailed Solution for Test: Concentration of Solutions, Vapour pressure - Question 11
A solution of acetone in ethanol shows positive deviation from Raoult's law. It is because ethanol molecules are strongly hydrogen bonded. When acetone is added, these molecules break the hydrogen bonds and ethanol becomes more volatile. Therefore its vapour pressure is increased.

An aqueous solution is molal in KI. Which change will cause the vapour pressure of the solution to increase?
Detailed Solution for Test: Concentration of Solutions, Vapour pressure - Question 12
When the aqueous solution of one molal is diluted with water, concentration decreases, therefore the vapour pressure of the resulting solution increases.

Which of the following is true regarding azeotropes?
Detailed Solution for Test: Concentration of Solutions, Vapour pressure - Question 15
Azeotropes have the same concentration in the vapour phase and the liquid phase. In case of minimum boiling azeotropes, the boiling point of the azeotrope is lesser than the booling point of either of the pure components. In case of maximum boiling azeotropes, the boling point of the azeotrope is higher than the boiling point of either of the pure components.
