Q.
The complex that dissolves in water is [2023]

1 ${({NH}_{4})}_{3} [As {({Mo}_{3} O_{10})}_{4}]$

2 $K_{3} [Co {({NO}_{2})}_{6}]$

3 $[{Fe}_{3} {(OH)}_{2} {(OAc)}_{6}] Cl$

4 ${Fe}_{4} {[Fe {(CN)}_{6}]}_{3}$

Ans.
(3)

${Fe}_{4} {[Fe {(CN)}_{6}]}_{3}$ Prussian Blue -- water insoluble

$K_{3} [Co {({NO}_{2})}_{6}] \Rightarrow$ very poorly water soluble

${({NH}_{4})}_{3} [As {({Mo}_{3} O_{10})}_{4}]$ water insoluble

ammonium arsenomolybdate

$[{Fe}_{3} {(OH)}_{2} {(OAc)}_{6}] Cl$ is water soluble.

Solution

Q. The complex that dissolves in water is [2023]

1 (NH4)3[As(Mo3O10)4]

2 K3[Co(NO2)6]

3 [Fe3(OH)2(OAc)6]Cl

4 Fe4[Fe(CN)6]3

Ans. (3) Fe4[Fe(CN)6]3 Prussian Blue -- water insoluble K3[Co(NO2)6] ⇒ very poorly water soluble (NH4)3[As(Mo3O10)4] water insoluble ammonium arsenomolybdate [Fe3(OH)2(OAc)6]Cl is water soluble.
