A) \[20ml\] of \[0.1M\] \[FeS{{O}_{4}}\]
B) \[30ml\] of \[0.1M\] \[FeS{{O}_{4}}\]
C) \[40ml\] of \[0.1M\] \[FeS{{O}_{4}}\]
D) \[50ml\] of \[0.1M\] \[FeS{{O}_{4}}\]
Correct Answer: D
Solution :
In this reaction \[\underset{1}{\mathop{MnO_{4}^{-}}}\,+\underset{5}{\mathop{5F{{e}^{2+}}}}\,+8{{H}^{+}}\to M{{n}^{2+}}+5F{{e}^{3+}}+4{{H}_{2}}O\] 5 time quantity of \[F{{e}^{2+}}\] consumed. So 5 time of \[FeS{{O}_{4}}\] will be equivalent to 50 ml
