$Mg(OH)_2$

Vedclass · Answer

(C) Temporary hardness due to $Mg(HCO_3)_2$ is removed by boiling.
Upon heating,$Mg(HCO_3)_2$ decomposes to form magnesium hydroxide $(Mg(OH)_2)$ precipitate rather than magnesium carbonate $(MgCO_3)$ because $Mg(OH)_2$ is less soluble than $MgCO_3$ in water.
The reaction is: $Mg(HCO_3)_{2(aq)} \xrightarrow{\Delta} Mg(OH)_{2(s)} + 2CO_{2(g)}$.

When temporary hard water containing $Mg(HCO_3)_2$ is boiled,the precipitate formed is of:
