A) 10
B) 8
C) 6
D) 3
Correct Answer: A
Solution :
The balanced chemical equation of the oxidation of oxalic acid is as under: \[2KMn{{O}_{4}}+3{{H}_{2}}S{{O}_{4}}+5\underset{COOH}{\mathop{\underset{|}{\mathop{COOH}}\,}}\,\xrightarrow{{}}\] \[{{K}_{2}}S{{O}_{4}}+2MnS{{O}_{4}}+10C{{O}_{2}}+8{{H}_{2}}O\] From the above equation it is clear that in . balanced chemical equation of oxidation o oxalic acid by KMn04 in acidic medium evolve 10 molecules of \[C{{O}_{2}}.\]You need to login to perform this action.
