Temporary hardness is caused by dissolved calcium hydrogencarbonate (which is removed by boiling). Permanent hardness is caused by dissolved calcium sulfate (which is notremoved by boiling). Water can be softened using washing soda or an ion-exchange resin
so basically temporary hardness in water can be removed by the addition of washing soda

Heyyy..here is ur answer... ⬇️
May it helps uh....☺
Temporary hard water contains slightly soluble calcium bicarbonate. Calcium carbonate is essentially insoluble, but water that contains CO2 can dissolve a little CaCO3 to give Ca(HCO3)2. This is “hard” on soap. Bicarbonate loses CO2 to air and the calcium carbonate precipitates again in caves giving stalactites and stalagmites. You can accelerate this process by heating the water; the CaCO3 formed will precipitate out and the water will be less hard, maybe soft enough.
