A) 2 5 16
B) 16 5 2
C) 5 16 2
D) 2 16 5
Correct Answer: A
Solution :
Oxidation reaction\[{{C}_{2}}O_{4}^{2-}\xrightarrow[{}]{{}}2C{{O}_{2}}+2{{e}^{-}}]\times 5\] Reduction reaction \[MnO_{4}^{-}+8{{H}^{+}}+5{{e}^{-}}\xrightarrow[{}]{{}}M{{n}^{2+}}+8{{H}_{2}}O]\times 2\] Net reaction \[=2MnO_{4}^{-}+16{{H}^{+}}+5{{C}_{2}}O_{4}^{2-}\xrightarrow[{}]{{}}2M{{n}^{2+}}\]\[+10C{{O}_{2}}+8{{H}_{2}}O\]You need to login to perform this action.
