Answer 2

$MgCl_2+Na_2CO_3\rightarrow MgCO_3+2NaCl$

$MgCO_3+Ca(OH)_2\rightarrow CaCO_3+Mg(OH)_2$

Explanation:

Permanent hardness is the hardness caused by chlorides and sulfates of calcium and magnesium. It is also called as no carbonate hardness as it only be removed using chemical methods.

Example: $MgCl_2$ and $MgSO_4$

The equation for softening of $MgCl_2$ is:

$MgCl_2+Na_2CO_3\rightarrow MgCO_3+2NaCl$

$MgCO_3+Ca(OH)_2\rightarrow CaCO_3+Mg(OH)_2$

The equation for softening of $MgSO_4$ is:

$MgSO_4+Na_2CO_3\rightarrow MgCO_3+Na_2SO_4$

$MgCO_3+Ca(OH)_2\rightarrow CaCO_3+Mg(OH)_2$
