Answer:
Sodium carbonate can remove temporary and permanent hardness from water. Sodium carbonate is soluble but calcium carbonate and magnesium carbonate are insoluble.
The carbonate ions from sodium carbonate react with the calcium and magnesium ions in the water to produce insoluble precipitates.
Ca+2(aq.)+Na2CO3(aq.)⟶CaCO3(s)+2Na+(aq.)
Mg+2(aq.)+Na2CO3(aq.)⟶MgCO3(s)+2Na+(aq.)
