Vedclass · Answer

(D) Temporary hardness of water is caused by the presence of dissolved bicarbonates of calcium and magnesium,specifically $Ca(HCO_3)_2$ and $Mg(HCO_3)_2$.These can be removed by boiling,which converts them into insoluble carbonates:$Ca(HCO_3)_2 \rightarrow CaCO_3 \downarrow + H_2O + CO_2$$Mg(HCO_3)_2 \rightarrow MgCO_3 \downarrow + H_2O + CO_2$
