Water molecules are polar. Charged particles such as ions attract water molecules. Positive ions often have a "shell" of water molecules around them, pointing their negative O atoms at the central ion, both in solution and in the solid forms (hydrates)

Why do charged and polar molecules dissolve in aqueous solutions?
Because water is polar, and polar solvants will dissolve polar solutes. :)
How many bonds are in water?
There are 2 bonds in water(H2O) but molecules of water will interact with each other through hydrogen bonding.
How does water interact with non polar substances?
Water does not interact well with nonpolar substances because they do not have large enough dipoles to cause water to interact with them and not other water molecules. Water is said to squeeze nonpolar molecules together because of the hydrophobic effect it of nonpolar compounds.
What is the charge on a solute molecule surrounded by a hydration shell of water?
Solute molecules can be positively charged, negatively charged, or neutral. For example, dissolving sodium chloride in water produces positively charged sodium cations and negatively charged chloride anions. Dissolving sucrose (table sugar) in water produces only dissolved neutral sucrose molecules.
When water molecules dissociate into two charged particles they are called?
Hydrogen gas and Oxygwn gas
What does hydrophollic mean?
Refers to molecules, or portions of molecules, that interact with water and charged particles
Which molecules are able to interact with water?
Hydrophilic molecules
Molecules that are insoluble in water or do not readily interact with water are said to be?
Hydrophobic.
Which atom in the water molecule will interact with a positive ion?
The partially negatively charged oxygen atom in water will interact with a positive ion.
Are sugars non polar Molecules?
No, sugars are polar molecules considering that they will interact and dissolve in water (which is also a polar molecule). Polar molecules will only interact with other polar molecules and vice-versa.
What happens between the charged atoms when water interact with salt to cause the salt to dissolve in the water?
Both salt (NaCl) and water molecules have one atom that concentrates the negative ... The NaCl and H2O interact in such a way that the partial negative charge on O is ... This process works because the attraction between NaCl and H2O is ...
How many different molecules can one water molecule interact with?
2
What type of molecules mix the best with water?
Molecules that are polar(charged) dissolve best in water, while nonpolar molecules do not dissolve well in water.
What is a type of molecule that interact with water by dissolving in water and or forming hydrogen bonds with water molecules?
hydrophilic
Why do humans need h2o?
Water dissolves the molecules inside our cells and fills up our cells so they have a shape. The molecules like proteins and DNA need to be dissolved in water so that they can move around to the places where they are needed. Water is also a polar material, H2O has both positive and negative parts, and this polarization helps the molecules interact with each other.
Do honey molecules interact more stronger than water molecules?
No, honey molecules do not interact more strongly than water molecules. Honey is a syrupy liquid that is composed mostly of water molecules, along with other compounds such as sugars. The intermolecular forces between water molecules, such as hydrogen bonding, are generally stronger than the forces between honey molecules, making water more cohesive and having a higher surface tension than honey.
What type of organic molecule requires the action of emulsifiers to be sucessfully digested?
Fat molecules. Water molecule is polar, and therefore water is a good solvent for other polar molecules, dissolving them when they come in contact with one another. Water is not a good solvent for nonpolar molecules, such as fats. A fat has no polar grups to interact with water molecules. An emulsifier, however, can cause a fat to disperse in water. An emulsifier contains molecules with both polar and nonpolar ends. When the nonpolar ends interact with the fat and the polar ends interact with the water molecule, the fat disperses in water, and an emulsion results.
