The correct answer is: C. It has a high dipole moment.
A dipole moment is a measure of the separation of charge in a molecule. Water has a high dipole moment because the oxygen atom is more electronegative than the hydrogen atoms, which means that the electrons in the O-H bonds are shared unequally. This results in a partial negative charge on the oxygen atom and a partial positive charge on the hydrogen atoms.
Ionic salts are made up of positively charged ions (cations) and negatively charged ions (anions). The positive and negative charges of the ions are attracted to the oppositely charged ends of the water molecules, which causes the ions to dissolve in water.
The other options are not correct because:
- A. Water has a high specific heat, which means that it takes a lot of energy to raise its temperature. This is not related to its ability to dissolve ionic salts.
- B. Water has no color. This is not related to its ability to dissolve ionic salts.
- D. Water has a high boiling point. This is not related to its ability to dissolve ionic salts.
