$Cr_2S_3$

Vedclass · Answer

(D) $ZnS$,$MnS$,and $FeS$ do not dissolve in excess $NH_3$ solution due to their low $K_{sp}$ values.However,$Cr_2S_3$ can react with excess $NH_3$ to form a soluble complex: $Cr_2S_3 + 12NH_3 + 6H_2O \rightleftharpoons 2[Cr(NH_3)_6]^{3+} + 3S^{2-} + 6OH^-$. Note: In many standard contexts,$ZnS$ is also considered to form a soluble complex $[Zn(NH_3)_4]^{2+}$ in excess $NH_3$,but among the given choices,$Cr_2S_3$ is specifically noted for its reactivity in this context.
