Q5
Following reaction is used to remove temporary hardness which is due to dissolved bicarbonates of Ca2+ and Mg2+.

Ca(HCO3)2+Ca(OH)22CaCO3+2H2O

Actually lime (CaO) is added which in H2O forms Ca(OH)2 and precipitates CaCO3 CaO+H2OCa(OH)2

If 10 L of hard water requires 0.56 g of CaO, temporary hardness of CaCO3 is x×102 ppm. Find x.
