Answer
a. Vegetable oil is more likely to be soluble in $CCl_4$.
b. Oleic acid is more likely to be soluble in carbon tetrachloride $CCl_4$.
c. Niacin is more likely to be soluble in water.
d. $FeSO_4$ is more likely to be soluble in water.
Work Step by Step
- Ionic and polar solutes are more likely to be soluble in polar solvents, in this case, the polar solvent we have is water.
- Nonpolar solutes are more likely to be soluble in nonpolar solvents, in this case, the nonpolar solvent we have is carbon tetrachloride.
