Question

Listed below are possible solutes. In your possession is a beaker with 500 milliliters of water. You want to make an aqueous solution with the highest concentration of solute possible. Which two solutes could you mix with the water to achieve this?

I. Ammonia

I I. Hexane

I I I. Hexanol

I V. Octane

Answers:
I & II

I & III

II & III

II & IV

Answer 1

Answer: I & III

Explanation: Solutes are the substances which are minimum in quantity and which is required to dissolve in the solvent (which is larger in quantity) in order to make a solution.

In the asked question, it is given that the water is the solvent and from the given solutes we have to pick which would make an aqueous solution with the highest concentration of solute possible.

Thus the most appropriate answers could be the Ammonia and hexanol which can make the highest possible concentration of solute as ammonia is the gas which is highly soluble in water and hexanol is an alcohol which has an affinity for water. Thus the correct option is I & III
