Answer: Option (d) is the correct answer.
Explanation:
A precipitate is a substance which forms whenever two aqueous solutions chemically combine with each other.
For example, [tex]HCl(aq) + AgNO_{3}(aq) \rightarrow AgCl(s) + HNO_{3}(aq)[/tex]
A precipitate is a solid which is insoluble in a liquid. Silver chloride is an insoluble solid in water also. Whereas RbF, [tex]FeCl_{2}[/tex] and [tex]CaF_{2}[/tex] are ionic compound and these are highly soluble in water.
[tex]Al_{2}O_{3}[/tex] is slightly soluble in water as it is a covalent compound.
Therefore, we can conclude that out of the given options AgCl solutes is most likely to have low water solubility due to the dissolution process being highly endothermic.
