Question

3. Why is the dielectric constant a significant parameter for solubility? 4. For each of the following pairs of solures and solvent, predict whether the solute would be soluble or insoluble. After making your predictions, you can check your answers by looking up the compounds in The Merck Index or the CRC Handbook of Chemistry and Physics. The Merck Index is the easier reference book to use or just visit our Computer Lab located at AC-I Room 368 and perfornm the correct analysis using the Spartan software a) Malic acid in water b) Naphthalene in water c) Amphetamine in cthyl alcohol d) Aspirin in water c) Ibuprofen in dicthyl ether

Explanation / Answer

3.Dielectric constant of a solvent is measure the power of a solvent to weak the coulombic forces of attraction among the solute molecules existing.A good solvent have high value of dielectric constant and vice-versa.4. Maleic acid is soluble in water.(b)naphthalene is insoluble in water.(c) amphetamine is insoluble in ethyl alcohol(d)Aspirin is insoluble in water(e)Ibuprofen is insoluble in diethyl ether.
