* Na₂CO₃: This represents sodium carbonate, a white, water-soluble ionic compound.
* ·10H₂O: This indicates that the sodium carbonate molecule is associated with ten water molecules. These water molecules are chemically bound to the sodium carbonate molecule, forming a hydrate.
Properties of sodium carbonate decahydrate:
* Appearance: Colorless, transparent crystals.
* Solubility: Very soluble in water.
* Uses: Washing soda has various uses, including:
* Laundry detergent: Helps soften hard water and boost cleaning power.
* Cleaning agent: Used for cleaning ovens, drains, and other surfaces.
* Water softener: Removes calcium and magnesium ions from water.
* Industrial applications: Used in glassmaking, paper production, and chemical synthesis.
Note: When heated, sodium carbonate decahydrate loses its water molecules and becomes anhydrous sodium carbonate (Na₂CO₃).
