Water (H20) is a polar covalent molecule with two highly electronegative oxygen atoms. The electronegative oxygen atoms create a dipole moment, and are also cause H20s bent shape.

Explain how a water molecule can be attracted to both a positive ion and a negative ion when dissolving an ionic compound?
The shape and charge distribution in a water molecule cause it to have a permanent dipole moment, which consist of a positive electric charge and a negative charge separated by a distance in space. Therefore, the part of a water molecule that corresponds to the negative charge of its dipole moment is attracted to positive ions, and the part of a water molecule that corresponds to the positive charge of its dipole moment is attracted to negative ions.
When sodium chloride is dissolved into water what part of the water molecule does sodium get attracted to?
The negative dipole of the oxygen
When NaCl is dissolved in water negative end of the water molecules is attracted towards what?
Ion-dipole attraction dictates that the negative pole of a water molecule will be attracted to the sodium cation and the positive pole of a water molecule will be attracted to the chloride anion.
Is H2o a dipole force?
Yes it is. there are lone pairs on the oxygen that induce the dipole moment
Why does hydrochloric acid though a covalent compound ionize?
HCl is strictly speaking - a polar covalent molecule with a partial positive charge on hydrogen and a partial negative charge on chlorine. When this is dissolved in water, water too being a polar molecule with a partial positive charge on hydrogen and a partial negative charge on oxygen, hydrogens of HCl are surrounded by oxygens of water forming dipole dipole bonds. So also the chlorines are surrounded by hydrogens of water. When the dipole-dipole bonds are formed, the original bond between H and Cl weakens and ultimately breaks leading to ionization.

What do you mean by Dipole Moment and Induced Dipole Moment?
Induced dipole forces result when an ion or a dipole induces a dipole in an atom or a molecule with no dipole. These are weak forces. An ion-induced dipole attraction is a weak attraction that results when the approach of an ion induces a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons in the nonpolar species. A dipole-induced dipole attraction is a weak attraction that results when a polar molecule induces a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons in the nonpolar species.

Ion-dipole attraction dictates that the negative pole of a water molecule will be attracted to the sodium cation and the positive pole of a water molecule will be attracted to the chloride anion.
Dipole moment vector of water molecule?
dipole moment of water is 1.85 Debye
What is an example of dipole dipole?
an example would be an O2 that meets water. The electrons in the O2 molecule all move to the opposite side of each atom, away from the negatively charged Oxygen in H2O, thus leaving a slightly negative charge on the side away from the H2O molecule and a slightly positive charge towards the H2O molecule. The positive attract the negative electrons in the water.
Why is a water molecle polar?
Water is polar due to the two sets of unbound electron pairs on the oxygen molecule which oppose the positivly charged hydrogen. This causes a dipole, a positive and negative end to the molecule.
Is H2o a dipole force?
Yes it is. there are lone pairs on the oxygen that induce the dipole moment
Describe the mechanisms of water transport?
Water coheres by forming intermolecular hydrogen bonds. The polar molecules line up; positive dipole to negative dipole. They form hydrogen bonds between the hydrogen molecules of one molecule and the filled orbitals of the next molecule's oxygen. Cohesion is the attraction of matching substances.

What type bond is responsible for holding one water molecule to another water molecule?
The intermolecular forces between water molecules are hydrogen bonds, a special (and much stronger) version of dipole-dipole bonds.
What is a H20 polar molecule?
It's just regular old water. All water is polar because the molecule has a dipole.
