sodiumwater
Sodiumwater is not a widely defined chemical term. In practice it may refer to any aqueous solution that contains sodium ions, but it is not a standard name for a specific compound. The most common interpretation is an aqueous solution of a sodium salt, especially sodium chloride in water, i.e., saline solution. In some contexts it may also denote transient hydrated sodium species or solvated sodium clusters studied in physical chemistry, which are not discrete, isolable compounds.
- Saline interpretation: a solution containing Na+ and Cl−, typically NaCl dissolved in water. Medical saline, for
- Other sodium salts: solutions can contain Na+ paired with various anions (such as NaOH, Na2SO4, etc.),
- Hydrated sodium species: in solution, sodium ions are surrounded by water molecules (hydration shells), but these
Physical and chemical properties
- Sodium-containing aqueous solutions are generally colorless and miscible with water.
- They conduct electricity due to dissolved ions.
- The pH depends on the accompanying anion: NaCl solutions are near neutral; NaOH in water yields
- The precise properties (osmolarity, conductivity, pH) vary with the dissolved salt and its concentration.
- Solutions of sodium salts are usually handled as standard chemical reagents with typical cautions for chemical
- Metallic sodium reacts vigorously with water, releasing heat and hydrogen gas; such a reaction is a
- Prepared by dissolving a sodium salt in water (for example, NaCl in water to make saline).
- Applications include medical IV fluids, food processing, and various laboratory reagents and electrolyte studies.
