Vedclass · Answer

(A) The correct matches are as follows:$A$. $Mg(HCO_3)_2 \rightarrow Mg(OH)_2 \downarrow + 2 CO_2 \uparrow$ is the reaction occurring during the removal of temporary hardness by $III$. Boiling.$B$. $M^{2+} + Na_4P_6O_{18}^{2-} \rightarrow [Na_2MP_6O_{18}]^{2-} + 2 Na^{+}$ is the reaction involved in $IV$. Calgon's method (using sodium hexametaphosphate).$C$. $Ca(HCO_3)_2 + Ca(OH)_2 \rightarrow 2 CaCO_3 + 2 H_2O$ is the reaction in $I$. Clark's method (adding lime).$D$. $2 NaZ + Ca^{2+}_{(aq)} \rightarrow 2 Na^{+} + CaZ_2$ is the reaction in $II$. Ion exchange method (using zeolite).Therefore,the correct sequence is $A-III, B-IV, C-I, D-II$.
