Boiling of hard water is helpful in removing the temporary hardness by converting calcium hydrogen carbonate and magnesium hydrogen carbonate to :
Solution
$$\mathrm{Ca}\left(\mathrm{HCO}_{3}\right)_{2} \stackrel{\Delta}{\longrightarrow} \mathrm{CaCO}_{3} \downarrow+\mathrm{H}_{2} \mathrm{O}+\mathrm{CO}_{2} \uparrow$$<br/><br/>
$$\mathrm{Mg}\left(\mathrm{HCO}_{3}\right)_{2} \stackrel{\mathrm{A}}{\longrightarrow} \mathrm{Mg}(\mathrm{OH})_{2}+2 \mathrm{CO}_{2} \uparrow$$
