A) 0. 2
B) 0. 4
C) 0. 8
D) 1. 0
Correct Answer: A
Solution :
\[\underset{+4}{\mathop{VO_{3}^{2-}}}\,\xrightarrow[{}]{{}}\underset{+5}{\mathop{VO_{4}^{3-}}}\,\underset{\text{1}\,\text{unit}}{\mathop{Change}}\,\] \[\underset{+7}{\mathop{MnO_{4}^{-}}}\,\xrightarrow[{}]{{}}\underset{+2}{\mathop{Mn_{{}}^{2+}}}\,5\,\text{unit}\] \[\therefore \] \[5VO_{3}^{2}\equiv 1MnO_{4}^{-}\] \[1\,VO_{3}^{2-}\,\equiv \,\frac{1}{5}\,MnO_{4}^{-}\,=0.2\]You need to login to perform this action.
