Question

Write a CHECK mark whether the given solute is soluble and a X If is not soluble in the given solvent

​

Answer 1

Answer:

-Octane is non polar and can dissolve non-polar solutes. It cannot dissolve polar (and ionic) solutes.

Cyclohexane is non-polar. Hence, easily soluble in n-octane.

Methanol and acetonitrile are polar and have very low solubility in n-octane.

KCl is ionic compound and hence, insoluble in n-octane.

The increasing order for solubility in n-octane is as follows:

KCl<CH

3

OH<CH

3

CN<Cyclohexane
