Sodium chloride is an ionic compound that consists of the cation Na+ and the anion Cl-. When these two ions are brought together in water, they will interact with the water molecules. The Na+ ions will be attracted to the negative oxygen atoms on the water molecules, while the Cl- ions will be attracted to the positive hydrogen atoms.
This attraction will cause the sodium chloride molecules to break apart and dissolve in the water.
Sodium chloride is an ionic compound, meaning it is made up of charged particles, or ions. When sodium chloride dissolves in water, the ions are pulled apart by the water molecules. The positive sodium ions are attracted to the negative oxygen atoms of the water molecules, while the negative chloride ions are attracted to the positive hydrogen atoms.
This process is called hydration.
How Does Sodium Chloride Dissolve?
Sodium chloride is an ionic compound, meaning it is made up of charged particles (ions). When sodium chloride is added to water, the ions are attracted to the water molecules. The water molecules surround the ions and pull them away from each other.
This process is called dissolution.
Why Does Sodium Chloride Dissolve Easily in Water?
Sodium chloride is an ionic compound made up of sodium and chlorine atoms. When these atoms come into contact with water, they dissociate into their respective ions: Na+ and Cl-. These ions are then surrounded by water molecules, which makes it easier for them to move around.
In other words, the addition of water molecules breaks up the attraction between the sodium and chlorine atoms, making it easier for them to move apart.
How Does Water Dissolve Sodium Chloride Nacl Quizlet?
Water is a polar molecule, meaning that it has a slightly positive charge on one side and a slightly negative charge on the other. This gives water the ability to dissolve ionic compounds, like sodium chloride (NaCl). When NaCl is added to water, the ions are pulled apart by the water molecules.
The positively-charged sodium ions are attracted to the negative oxygen atoms of the water molecules, while the negatively-charged chlorine ions are attracted to the positive hydrogen atoms.
What Happens When Sodium Chloride is Placed in Water?
When sodium chloride is placed in water, the sodium and chloride ions separate and dissociate. The sodium ion is attracted to the water molecules because it is a polar molecule. The chloride ion is also attracted to the water molecules, but not as much as the sodium ion.
As a result, the sodium chloride molecules are pulled apart by the water molecules and dissociate into their individual ions.
Sodium Chloride Dissolved in Water Equation
When sodium chloride is dissolved in water, the resulting solution is a mixture of Na+ ions and Cl- ions in water. The overall chemical reaction can be represented by the following equation:
NaCl(s) + H2O(l) → Na+(aq) + Cl-(aq)
This equation simply states that when sodium chloride dissolves in water, it forms a solution of Na+ and Cl- ions. In reality, this process is a bit more complicated than that. When salt (or any ionic compound) dissolves in water, it undergoes what is known as hydrolysis.
Hydrolysis is a type of chemical reaction where the compound reacts with water to form new compounds. In the case of NaCl, hydrolysis results in the formation of hydroxide (OH-) and chlorine (Cl2) molecules:
NaCl(s) + H2O(l) → NaOH(aq) + HCl(aq)
The overall equation for the dissolution of sodium chloride can be written as:
NaCl(s)+H 2 O→Na+(aq)+OH−1+(aq)+HCL1−3.(aq).
Conclusion
Sodium chloride is a chemical compound with the formula NaCl, representing table salt. It is composed of one sodium atom and one chlorine atom connected by ionic bonding. Sodium chloride is a very strong electrolyte and is highly soluble in water.
When sodium chloride dissolves in water, the sodium and chlorine atoms separate and form ions. The sodium ions are attracted to the negative end of the water molecules, while the chlorine ions are attracted to the positive end. This process creates an electric field that helps to keep the ions suspended in solution.
