C) \[N{{i}^{2+}}\]
D) \[M{{n}^{2+}}\]
Correct Answer: B
Solution :
\[F{{e}^{2+}}+{{H}_{2}}S\xrightarrow{{}}\underset{Black\,ppt.}{\mathop{FeS}}\,+2{{H}^{+}}\] \[FeS+2HCl\xrightarrow[{}]{{}}\underset{So\operatorname{lub}le}{\mathop{FeC{{l}_{2}}}}\,+{{H}_{2}}S\]You need to login to perform this action.
