First there are three sides of a molecule there are 2 hydrogen sides and 1 oxygen side. The oxygen end has a slight negative charge, and the hydrogen end has positive charge. A molecule that has electrically charged areas is a polar molecule. Because water consists of polar water molecules, it is called a polar substance.

∙ 13y agoIn covalent bonds individual atoms share electrons with one another forming compounds. A Water molecule is made up of one oxygen atom and two hydrogen atoms covalently bonded together. The oxygen atom is larger and the hydrogens are attached to it, near each other with the appearance of "Mickey Mouse ears". Because the oxygen atom has a greater number of protons, it develops a slightly negative charge since the electrons spend more time with the oxygen (Mickey's Head). This means the negatively charged electrons spend less time around the two hydrogen atoms, and these two hydrogen atoms (Mickey's ears) become slightly positive.

When placed between oppositely charged metal plates the region of a water molecule attracted to the negative plate is what?
partially positively charged hydrogen end of the molecule.
What explains the solubility of ionic substances in water?
Ionic substances dissolve in water because of the attraction exerted between positive ions and the negatively charged oxygen part of the water molecule, and also between negative ions and the positively charged hydrogen part of the water molecule.
What is A molecule with one end positively charged and one end negatively charged?
its called a Zwitter ion, malic acid in pH 7 is a zwitter ion
Is salt a hydrophilic or hydrophobic?
No. Instead, salt is hydrophilic ("water-loving"). Salt (NaCl, or Na+ and Cl-) is very attracted to Water (H20, or H2+ and O-) because opposite electrostatic charges attract. The anionic ("negatively charged") Chlorine end of the salt molecule is attracted to the 2 cationic ("positively charged") Hydrogen ions of the water molecule: Cl- wants H2+. In the same way, the cationic Sodium end is attracted to the anionic Oxygen end: Na+ wants O-. Since each end of the salt molecule is attracted to the reciprocal end of the water molecule, there is a strong overall molecular attraction.
Why can't sodium chloride dissolve in gasoline?
Sodium chloride is an ionic compound which when it dissolves forms positively charged sodium ions and negatively charged chloride ions, therefore, it dissolves in what are known as polar solvents, of which water is the best example; the asymetrical water molecule has a positively charged end and a negatively charged end (the two hydrogen atoms attach to the oxygen atom at roughly a 120 degree angle) and therefore there is a strong attractions that takes place between ions and water molecules, which orient themselves so that oppositely charged ends of the molecule face a given ion, creating an electrostatic attraction in accordance with Coulomb's Law. In comparison, gasoline is what is known as a non-polar solvent; the molecules do not have any charged poles, all sections of the molecule are electrically neutral, and so these molecules have no basis upon which to attract ions. Hence, the ions remain attached to each other - the solium attaching to the chlorine, in this example - rather than to gasoline molecules.
What major property of water helps it hold molecules together?
Water is a "polar" molecule; one end of the molecule is negatively charged while the other end is positively charged.
When placed between oppositely charged metal plates the region of a water molecule attracted to the negative plate is what?
partially positively charged hydrogen end of the molecule.
How is water an example of polar molecule?
The oxygen atom, which is negatively charged, is on one end ("pole") of the molecule, and the hydrogen atoms, which are positively charged, are on the other pole.
When placed between oppositely charged metal plates the region of a water molecule that is attracted to the negative plate is the .?
partially positively charged hydrogen end of the molecule.
Water is a polar molecule?
Yes. The oxygen end is slightly negatively charged, and the hydrogen end is slightly positively charged.
How are water molecules like magnets?
water molecules are polar (there is an unequal charge around the molecule) The oxygen end of the water molecule is negatively charged and the hydrogen ends of the water molecule is positively charged. thus, the oxygen will attract positive atoms and the hydrogens will attact negative atoms
Which end of the water molecule is attracted to the sodium ion?
Since water is a slightly polar molecule (the hydrogen end being slightly positive and the oxygen ends being slightly negative) the positively charged sodium ion (Na+) will be attracted to the oxygen end of the water molecule.
How do you describe water's polarity?
Due to the uneven distribution of the electron density, water is considered a polar molecule. The oxygen atom is more negatively charged at one end of the water molecule while the hydrogen atom at the other end is positively charged. The net result of these charges gives water its polarity.
What is a molecule with a positively charged end and a negatively charged end?
its called a Zwitter ion, malic acid in pH 7 is a zwitter ion
What is different between polar and non-polar molecules?
A polar molecule is one that has a negatively charged end and a positively charged end, which form poles. A non-polar molecule doesn't.
A molecule that is positively charge on one end and negatively charged on the other end is called a nonpolar?
A polar molecules
What explains the solubility of ionic substances in water?
Ionic substances dissolve in water because of the attraction exerted between positive ions and the negatively charged oxygen part of the water molecule, and also between negative ions and the positively charged hydrogen part of the water molecule.
