A) 0.00380
B) 0.000469
C) 0.0095
D) 0.0183
Correct Answer: B
Solution :
\[Zn[Hg{{(NCS)}_{4}}\,\rightleftharpoons \,Z{{n}^{+2}}\,+[{{(Hg\,{{(NCS)}_{4}}]}^{2-}}\]\[\Rightarrow \,{{K}_{SP}}={{S}^{2}}\]\[\Rightarrow \,\,S=\sqrt{22\times {{10}^{-8}}}\,=4.69\times {{10}^{-4}}\,mol/L\]You need to login to perform this action.
