Question

page(s) 51-53 3.5. explain the difference between hydrophilic and hydrophobic molecules and between acids and bases. which of the following are hydrophilic? hydrophilic drag appropriate answer(s) here ions polar molecules nacl nonpolar molecules not hydrophilic drag appropriate answer(s) here

Explanation:

Hydrophilic substances interact favorably with water (a polar molecule). Ions are charged and attract water's polar molecules. Polar molecules have a dipole and interact with water. NaCl (sodium chloride) dissociates into ions in water, so it's hydrophilic. Nonpolar molecules lack a dipole and don't interact well with water, so they're not hydrophilic.

Answer:

Hydrophilic: ions, polar molecules, NaCl
Not Hydrophilic: nonpolar molecules
