Uses of sodium carbonate:

  • Due to its alkaline properties, sodium carbonate has an emulsifying effect on grease and dirt and hence, it is used as a cleaning material.
  • It is used to make hard water soft as it precipitates out the soluble calcium and magnesium salts in hard water as carbonates.

For example: Ca(HCO3)2(aq) + Na2CO3(aq) → CaCO3(s) + 2NaHCO3(aq)

  • It is used for commercial production of soap and caustic soda.
  • Sodium carbonate is used as an important laboratory reagent.
