A) \[Ca\]
B) \[Ba\]
C) \[Al\]
D) \[Zn\]
Correct Answer: D
Solution :
\[Z{{n}^{2+}}+2N{{H}_{4}}OH\xrightarrow{{}}\underset{White\,ppt.}{\mathop{Zn{{(OH)}_{2}}}}\,+2NH_{4}^{+}\] \[Zn{{(OH)}_{2}}+2N{{H}_{4}}OH\xrightarrow{{}}\underset{\text{Soluble}}{\mathop{{{(N{{H}_{4}})}_{2}}Zn{{O}_{2}}}}\,+2{{H}_{2}}O\] \[{{(N{{H}_{4}})}_{2}}Zn{{O}_{2}}+{{H}_{2}}S\xrightarrow{{}}\underset{White\,ppt.}{\mathop{ZnS}}\,+2N{{H}_{4}}OH\]You need to login to perform this action.
