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.
This is because the H2O has a positive side and a negative side. The negative Oxygen side will attract to positive the positive Hydrogen side will attract to negative. it has two sides because it is a bent molecule.
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.
Water is a highly polar molecule which means that one side of the molecule is slightly positive and the other is slightly negative. This means that water molecules are attracted and can form weak bonds with molecules that also have positive sides and negative sides (polar molecules). Basically, the positive side of the water molecule is attracted to the negative side of the polar molecule and the negative side of the water molecule is attracted to the positive side of the polar molecule. Is this way the water is able to surround and separate the polar molecules. The story is much the same for an ionic compound which contains a mixture of positive and negative ions. The positive side of the water molecules surround the negative ions and the negative side of the water molecules surround the positive ions.
Surrounds the ions with the hydrogen, positive end, attracted to the negative ion ( Cl -, for instance ) and the oxygen, negative end, attracted to the positive ion ( Na +, for instance ).
There is no such thing. A positive molecule will only be attracted to a negative molecule.
A cationic molecule is a positively charged ion. It is attracted to the cathode, or the negative pole, during electrolysis.
Water is a polar molecule meaning the oxygen part is negative the hydrogen is positive, so in an ionic compound the negative ion get attracted to the hydrogen and the positive ion to the oxygen.
Hydrogen Bonding and simply positive/negative attractive forces. The negative Oxygen atom of one water molecule is attracted to a positive Hydrogen atom of another water molecule.
It is the hydrogen portion of the water molecule which is attracted to a negatively charged plate.
The oxygen end,which is a negative pole
Water molecules are polar in character, they possess a dipole. The positive part of the water molecule is attracted to the negative ion in the ionic substance, and the negative part of the water molecule to the positive ion. The resulting release of energy encourages the process of dissolving. The solubility of ionic substances is variable and depends on other properties of the constituent elements.
Ionic compounds are made up of a positive cation (the metal) and a negative anion (the nonmetal). They are soluble in water because they can dissociate. The positive cations are attracted to the negative oxygen side of water molecules while the negative anions are attracted to the positive hydrogen side of water molecules. Water is a polar molecule and pulls the ions that make up the compound away from each other, thus causing the compound to be soluble.
The negative dipole of the oxygen
The slightly negative end of one polar molecule will be attracted to the slightly positive, hydrogen end of another molecule.
partially positively charged hydrogen end of the molecule.
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.
Water is a polar molecule due to its "bent" geometrical construction. - O / \ H H + + This construction allows it when ions bump into it to drag different things off. So if NaCl were to bump into this the Na would be attracted to the negative side whereas the Cl would be attracted to the positive side splitting the molecule and causing it to dissolve into the water.
Water dissolves substances because it's hydrogen bonds make it a polar molecule. Thus, the positive and negative ends of the water molecules attract the negative and positive ends (respectively) of substances, thus pulling them apart and dissolving the substance. Oil, however, is a nonpolar substance, so it is not attracted to the polarity of water.
Water molecules dont necessarily dissolve in water. Because water is a polar molecule, it has a slightly positive and slightly negative side to each molecule. The positive and negative sides of each water molecule are attracted to other positive and negative sides of other water molecules.
The chemistry of organic compounds is complex, but in general, the properties of an organic compound are determined by both the shape of the molecule and the pattern of positive and negative charges that exist in that molecule because of the varying electronegativity of the components of that molecule.
The oxygen atom is in the "middle" of the water molecule and has a slight negative charge. Refer to the related link below.
The water molecule is a polar molecule and therefore is referred to as slightly electro negative. This electro negativity explains the extra energy required to bring water to the boiling point compared to what would be expected from a molecule of its mass alone. The area of a water molecule that is electro negative will be attracted to the polar opposite side of another water molecule.
there is no such thing as a non polar end, the whole molecule is either polar or nonpolar. in a polar molecule, the negative end has the purpose of being attracted and combining with the positive end of another polar molecule; if that's what you meant.
