The solubility of table salt NaCl in water at room temperature 25C and pressure 1 atm is approximately 357 grams per liter g/L . This solubility is influenced by the type of chemical bond present in NaCl, which is an ionic bond.An ionic bond is formed between a metal sodium, Na and a non-metal chlorine, Cl due to the transfer of electrons from the metal to the non-metal. In the case of NaCl, sodium loses one electron to become a positively charged ion Na+ , and chlorine gains one electron to become a negatively charged ion Cl- . The electrostatic attraction between these oppositely charged ions forms the ionic bond.The solubility of NaCl in water can be explained by the interaction between the ions in the salt and the polar water molecules. Water is a polar solvent, meaning it has a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom. This polarity allows water to dissolve ionic compounds like NaCl through a process called solvation.When NaCl is added to water, the negatively charged oxygen atoms in water molecules surround the positively charged Na+ ions, while the positively charged hydrogen atoms in water molecules surround the negatively charged Cl- ions. This interaction between water molecules and the ions in NaCl weakens the electrostatic forces holding the ions together, allowing them to separate and disperse throughout the solution.The solubility of NaCl in water is influenced by several factors, including:1. Temperature: As temperature increases, the kinetic energy of water molecules also increases, which in turn enhances their ability to break the ionic bonds in NaCl. As a result, the solubility of NaCl generally increases with increasing temperature.2. Pressure: The solubility of NaCl in water is not significantly affected by pressure, as it is a solid solute. Pressure has a more pronounced effect on the solubility of gases in liquids.3. Presence of other ions: The solubility of NaCl can be affected by the presence of other ions in the solution. For example, the presence of ions with similar charges can lead to competition for solvation, which may decrease the solubility of NaCl.In summary, the solubility of table salt NaCl in water at room temperature and pressure is approximately 357 g/L, and it is influenced by the ionic bond present in NaCl. The solubility is mainly determined by the interaction between the ions in the salt and the polar water molecules, with temperature, pressure, and the presence of other ions also playing a role.
