Question

The attraction between water molecules and a na+ ion or a cl- ion occurs because water molecules are —

Answer 1

Water molecules are polar (positive charge zones and negative charge zones) this makes the attraction of a na+ ion or a cl- ion to occur.

How are the water molecules composed?

This class of molecules that have a distribution of charges are called polar and, consequently, form bonds called hydrogen bonds with other molecules.

These molecules have a permanent dipole moment, that is, they have a structure called dipolar (two poles), this arrangement gives water great power to dissolve substances within it.

Therefore, we can conclude that water molecules are polar (positive charge zones and negative charge zones) this makes the attraction of a na+ ion or a cl- ion to occur.
