What kind of bond does these have?

1. tap water

2. distilled water

3. sugar

4. salt

5. salt in distilled water

6. sugar in distilled water

1. Tap water has a small concentration of H + & OH - ions as well as water molecules, hence there would be permanent dipole-permanent dipole (p. d.-p. d.) forces of attraction between the water molecules (aka H-bonds) as well as ionic bonds between the H + & OH - ions.

2. Distilled water does not have H + & OH - ions, hence only H-bonds exist between the water molecules.

3. There are covalent bonds between the individual sugar molecules.

4. There are ionic bonds between the Na + & Cl - ions in NaCl.

5. There are p. d.-p. d. forces of attraction between the Na + ions and the O2 - partial ions of the water molecules as well as between the Cl - ions and the H + partial ions of the water molecules. There are also H-bonds between the individual water molecules and ionic bonds between the Na + & Cl - ions (although these are in much lower abundance than in unsolvated solid NaCl).

6. There are i. d.-i. d. as well as p. d.-p. d. forces of attraction between the sugar molecules and the water molecules. There are also H-bonds between the individual water molecules and covalent bonds within the sugar molecules.
