Water molecules are attracted to sodium chloride (table salt) because of the positive and negative charges present in the salt crystal lattice. The oxygen atom in water has a partial negative charge, while the hydrogen atoms have partial positive charges. This allows water molecules to interact with the positive sodium ions and negative chloride ions in the salt through electrostatic interactions, forming a hydrated salt solution.

How hydrogen bonds allow water to act as a solvent to dissolve sodium chloride?
Hydrogen bonds in water molecules interact with the ions in sodium chloride, breaking apart the ionic bonds that hold the sodium and chloride ions together. The partially positive hydrogen atoms in water molecules are attracted to the negatively charged chloride ions, while the partially negative oxygen atoms in water molecules are attracted to the positively charged sodium ions. This interaction results in the dissolution of sodium chloride in water.
Is Water and sodium chloride are example of inorganic molecules?
Yes, water and sodium chloride are examples of inorganic molecules. Inorganic molecules do not contain carbon-hydrogen (C-H) bonds and are typically derived from non-living matter. Water (H2O) consists of hydrogen and oxygen atoms, while sodium chloride (NaCl) is composed of sodium and chlorine ions.
What type of intermolecular force causes the dissolution of NaCl in water?
Ionic bonding between the sodium and chloride ions in NaCl is broken when the compound is dissolved in water. The partially positively charged hydrogen atoms in water molecules are attracted to the negatively charged chloride ions, and the partially negatively charged oxygen atoms are attracted to the positively charged sodium ions, allowing the ions to separate and be surrounded by water molecules.
Sodium chromate how many water molecules per formula?
Sodium chromate usually does not contain any water molecules per formula. The formula for sodium chromate is Na2CrO4, which does not have any water molecules associated with it.
Why is a water molecule more attracted to calcium ion than sodium ion?
A water molecule is more attracted to a calcium ion than a sodium ion because calcium has a larger positive charge than sodium, leading to stronger electrostatic interactions between water molecules and the calcium ion. Additionally, calcium has a smaller size compared to sodium, allowing water molecules to get closer to the calcium ion and form stronger bonds.
Why are water molecules so attracted to sodium chloride?
Water molecules are attracted to sodium chloride through hydrogen bonding and electrostatic interactions. The partially positive hydrogen atoms in water are attracted to the negatively charged chlorine ions in sodium chloride, forming a strong bond. Additionally, water helps to separate the sodium and chloride ions, allowing them to dissolve and disperse evenly throughout the solution.
How hydrogen bonds allow water to act as a solvent to dissolve sodium chloride?
Hydrogen bonds in water molecules interact with the ions in sodium chloride, breaking apart the ionic bonds that hold the sodium and chloride ions together. The partially positive hydrogen atoms in water molecules are attracted to the negatively charged chloride ions, while the partially negative oxygen atoms in water molecules are attracted to the positively charged sodium ions. This interaction results in the dissolution of sodium chloride in water.
What is the structure of sodium chloride and water?
The crystalline structure of sodium chloride is face-centered cubic.
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.
How does salt desolve in water?
Salt dissolves in water through a process called dissolution, where the salt molecules break apart and disperse evenly among the water molecules. This happens because water is a polar solvent, meaning it has positively and negatively charged ends that can attract and surround the charged ions in salt, causing them to separate and mix with the water.
When table salt sodium chloride (NaCl) is placed in water?
When table salt, sodium chloride (NaCl), is placed in water, it dissociates into its ions: sodium (Na+) and chloride (Cl-). These ions become solvated by water molecules and are dispersed uniformly throughout the solution. This forms a homogeneous mixture known as a solution.
can sodium and chlorine in water retain an electric charge?
Salt is sodium chloride. ... When the sodium chloride dissolves in water, the sodium atoms and chlorine atoms separate under the influence of the water molecules. They're free to move around in the water as positively and negatively charged ions. This separation of charge allows the solution to conduct electricity.
What happens to salt molecules when dissolved in water?
The salt molecules are "torn apart" by the water, and are reduced to sodium (Na+) and chlorine (Cl-) ions. It is the ions that go into solution and "float around" there. Note that elemental sodium and elemental chlorine are not what is in solution. The ions are. Salt, sodium chloride, is an ionic molecule; an ionic bond holds salt together.
Which is densersea water or water?
Sea water is slightly denser than fresh water as it contains dissolved salts. E.g. Sodium chloride (table salt) separates into sodium and chloride ions*, which water is attracted to**. Hence more molecules are packed into one area. *Ions are atoms that have lost or gained electrons. In this case the chlorine atom takes an electron from sodium giving it a negative charge, and leaving sodium with a positive charge. **Water is attracted to these charges because the oxygen atom draws the electrons from the hydrogen atoms giving it a slight negative charge and the hydrogen atoms a slight positive charge. This means that water is attracted to any charged molecule or ion.
When sodium chloride is dissolved into water what part of the water molecule does sodium get attracted to?
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.
Is fat polar?
Fats and oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water. Sodium and chloride ions are attracted to charged regions on molecules of polar solvents such as water.
How do water molecules dissolve in salt?
The salt molecules are "torn apart" by the water, and are reduced to sodium (Na+) and chlorine (Cl-) ions. It is the ions that go into solution and "float around" there. Note that elemental sodium and elemental chlorine are not what is in solution. The ions are. Salt, sodium chloride, is an ionic molecule; an ionic bond holds salt together.
