To find:
Which statement(s) about X and Y from the four options is (are) true?

Answer to Problem 11.1VP
Solution:
The true statement is “a.” X is the solvent in this solution.
Explanation of Solution
Generally the substance that is present in larger amount is called solvent, and solute is any component in a solution other than the solvent. Solute is generally in lower amount compared to the solvent. Also, the solvent often is volatile.
In the figure, we are given two components- X (blue sphere) and Y (red sphere). We can see that there are many more blue spheres than red spheres. Additionally, a few of the blue spheres are also present in vapor (gaseous) form above the mixture. Based on these observations, we can say that the blue spheres represent solvent particles and red spheres represent solute particles.
Based on the relative numbers and presence in vapor form, we can conclude that X is the solvent in this solution.
