Vedclass · Answer

(D) Hydrolysis is a reaction where water molecules break down a compound without changing the oxidation states of the elements involved.In the reaction $2F_{2(g)} + 2H_{2}O_{(l)} \rightarrow 4HF_{(aq)} + O_{2(g)}$,fluorine $(F_2)$ acts as a strong oxidizing agent.It oxidizes oxygen in water from $-2$ to $0$ (in $O_2$) and itself gets reduced from $0$ to $-1$ (in $HF$).Since this is a redox reaction and not a simple hydrolysis,option $D$ is the correct answer.

List-$I$ (Reactions)	List-$II$ (Methods)
$A$. $Mg(HCO_3)_2 \rightarrow Mg(OH)_2 \downarrow + 2 CO_2 \uparrow$	$I$. Clark's method
$B$. $M^{2+} + Na_4P_6O_{18}^{2-} \rightarrow [Na_2MP_6O_{18}]^{2-} + 2 Na^{+}$	$II$. Ion exchange method
$C$. $Ca(HCO_3)_2 + Ca(OH)_2 \rightarrow 2 CaCO_3 + 2 H_2O$	$III$. Boiling
$D$. $2 NaZ + Ca^{2+}_{(aq)} \rightarrow 2 Na^{+} + CaZ_2$ ($Z$ = Zeolite)	$IV$. Calgon's method
