Which one of the following solutes is most likely to have low water solubility due to the dissolution process being highly endothermic?

al2o3

rbf

caf2

agcl

fecl2

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,

A precipitate is a solid which is insoluble in a liquid. Silver chloride is an insoluble solid in water also. Whereas RbF, and are ionic compound and these are highly soluble in water.

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.

the answer is 1 i believe
