Adehesion
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.
Sodium chloride is dissociated in water being an ionic compound.
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.
The oxygen end of the water molecule is attracted to the Na+ ion. This attraction occurs due to the partial negative charge on the oxygen atom of the water molecule and the positive charge on the sodium ion.
what causes water molecules to be attracteed to one another
ionic
When sodium chloride is dissolved in water, the sodium ions are attracted to the partially negative oxygen atoms of water molecules. These oxygen atoms have a slight negative charge due to their higher electronegativity compared to hydrogen atoms. This attraction results in the formation of a hydration shell around the sodium ions.
When sodium chloride dissolves in water, the ions separate and become surrounded by water molecules. The sodium ion is positively charged and is attracted to the partially negative oxygen atom of the water molecule, forming an electrostatic bond. Likewise, the chloride ion is negatively charged and is attracted to the partially positive hydrogen atoms of the water molecule, forming another electrostatic bond. This results in each ion being surrounded by four water molecules, forming the hydration shell.
Sodium is attracted to water because water is a polar molecule, meaning it has a positive and negative end. The oxygen atom in water has a partial negative charge, so it attracts the positively charged sodium ion through electrostatic forces. This attraction allows sodium chloride to dissolve in water, with the sodium ion surrounded by water molecules.
When water is attracted to other water molecules it is called cohesion. When water is attracted to other substances it is called adhesion.
When water molecules are attracted to other water molecules, this is called COHESION. This is because the oxygen end of water has a negative charge and the hydrogen end has a positive charge. The hydrogens of one water molecule are attracted to the oxygen from the other water molecules. This is what causes Cohesion. :)
Sodium chloride is a hygroscopic compound.
