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.

How a water molecule can be attracted to both a positive and negative ion when dissolving an ionic compound?

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.


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.


What in water dissolves many ionic and molecular compounds?

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.


When an ionic molecule dissolves in water what does the water molecule do?

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 ).


What kind of molecule has two positive atoms attached to a positive atom?

There is no such thing. A positive molecule will only be attracted to a negative molecule.


What is a cationic molecule?

A cationic molecule is a positively charged ion. It is attracted to the cathode, or the negative pole, during electrolysis.


What are the characteristics of water that allows it to dissolve ionic solids?

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.


What explains why water molecules are attracted to each other?

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.


When placed between oppositely changed metal plates the region of a water molecule attracted to the negative plate is the?

It is the hydrogen portion of the water molecule which is attracted to a negatively charged plate.




Why are ironic substances soluble in water a polar solvent?

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.


Why are ionic compounds souble in water?

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.



How do polor molecules form hydrogen bonds?

The slightly negative end of one polar molecule will be attracted to the slightly positive, hydrogen end of another molecule.



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.


Why do ionic compound dissolve in water?

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.


Why does oil not dissolve in 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.


How do water molecules dissolve in 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.


What determines the properties of an organic compound?

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.



What is the middle in the water compound is it positive or negative?

The oxygen atom is in the "middle" of the water molecule and has a slight negative charge. Refer to the related link below.


Is water held together by opposite charges?

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.


What is the function of the nonpolar end of the soap 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.
