Vedclass · Answer

(B) The correct matches are as follows:$(A)$ Treatment with washing soda uses $Na_2CO_3$ to precipitate calcium and magnesium ions as carbonates. Thus,$A-II$.$(B)$ Calgon's method uses sodium hexametaphosphate,$Na_6P_6O_{18}$,which is known as Calgon. Thus,$B-IV$.$(C)$ Clark's method involves the addition of calculated amounts of lime,$Ca(OH)_2$,to remove temporary hardness. Thus,$C-I$.$(D)$ Zeolite/permutit process uses hydrated sodium aluminium silicate,$NaAlSiO_4$ (often represented as $Na_2Ze$),for ion exchange. Thus,$D-III$.Therefore,the correct sequence is $A-II, B-IV, C-I, D-III$.

List-$I$	List-$II$
$A$. Treatment with washing soda	$I$. $Ca(OH)_2$
$B$. Calgon's method	$II$. $Na_2CO_3$
$C$. Clark's method	$III$. $NaAlSiO_4$
$D$. Zeolite/permutit process	$IV$. $Na_6P_6O_{18}$
