A) \[2\text{ }M\text{ }HCl\]
B) \[\text{6 }M\text{ N}{{\text{H}}_{3}}\]
C) \[\text{6 }M\text{ NaOH}\]
D) \[{{\text{H}}_{2}}\text{S}\] gas
Correct Answer: B
Solution :
\[F{{e}^{3+}}+Z{{n}^{3+}}+C{{u}^{2+}}\xrightarrow{6MN{{H}_{3}}}\underset{Brown\,\,ppt.}{\mathop{Fe{{(OH)}_{3}}}}\,+\underset{\text{Soluble}}{\mathop{{{\left[ Zn{{\left( N{{H}_{3}} \right)}_{4}} \right]}^{2+}}}}\,\]\[\underset{\text{Soluble}}{\mathop{+{{\left[ Cu{{\left( N{{H}_{3}} \right)}_{4}} \right]}^{2+}}}}\,\]You need to login to perform this action.
