Select the ion exchange reaction, which proceeds to forward direction in aqueous medium

A
$2AgCl + Ca{F_2}\xrightarrow{{Aqueous}}2AgF + CaC{l_2}$
B
$BaS{O_4} + NaOH\xrightarrow{{Aqueous}}Ba{(OH)_2} + N{a_2}S{O_4}$
C
$Pb{(N{O_3})_2} + 2C{H_3}COONa\xrightarrow{{Aqueous}}Pb{(OAc)_2} + 2NaN{O_3}$
✓
$N{a_2}Cr{O_4} + BaC{l_2}\xrightarrow{{Aqueous}}BaCr{O_4} + 2NaCl$

✓

Answer

Correct option: D.

$N{a_2}Cr{O_4} + BaC{l_2}\xrightarrow{{Aqueous}}BaCr{O_4} + 2NaCl$

d
$(a)\,\mathop {2AgCl \downarrow }\limits_{(InSo\operatorname{lub} le)} + \mathop {Ca{F_2}(aq.)}\limits_{(InSo\operatorname{lub} le)} \xrightarrow{{Aqueous}}\mathop {2AgF(aq.)}\limits_{(So\operatorname{lub} le)} + \mathop {CaC{l_2}(aq.)}\limits_{(So\operatorname{lub} le)} $

$(b)\,\mathop {BaS{O_4} \downarrow }\limits_{(InSo\operatorname{lub} le)} + \mathop {2NaOH}\limits_{(So\operatorname{lub} le)} \xrightarrow{{Aqueous}}\mathop {Ba{{(OH)}_2}}\limits_{(So\operatorname{lub} le)} + \mathop {N{a_2}S{O_4}}\limits_{(So\operatorname{lub} le)} $

$(c)\,\mathop {Pb{{(N{O_3})}_2}}\limits_{(So\operatorname{lub} le)} + \mathop {2C{H_3}COONa}\limits_{(So\operatorname{lub} le)} \xrightarrow{{Aqueous}}\mathop {Pb{{(OAc)}_2}}\limits_{(So\operatorname{lub} le)} + \mathop {2NaN{O_3}}\limits_{(So\operatorname{lub} le)} $

$(d)\,\mathop {N{a_2}Cr{O_7}}\limits_{(So\operatorname{lub} le)} + \mathop {BaC{l_2}}\limits_{(So\operatorname{lub} le)} \xrightarrow{{Aqueous}}\mathop {BaCr{O_4}}\limits_{(InSo\operatorname{lub} le)} \downarrow + \mathop {2NaCl}\limits_{(So\operatorname{lub} le)} $
