A) 158
B) 31.6
C) 39.5
D) 79
Correct Answer: B
Solution :
\[5{{C}_{2}}O_{4}^{2-}+\overset{+\,\,7}{\mathop{2MnO_{4}^{-}}}\,+16{{H}^{+}}\to 10C{{O}_{2}}+2M{{n}^{2+}}\] \[+\,8{{H}_{2}}O\] Equivalent weight \[=\frac{\text{molecular}\,\text{weight}}{\text{change}\,\text{in}\,\text{oxidation}\,\text{number}}\] \[=\frac{158}{5}=31.6\]You need to login to perform this action.
