Question

For the redox reaction,

$xMnO_{4}^{-}+yH_{2}C_{2}O_{4}+zH^{+} \rightarrow mMn^{2 +}+nCO_{2}+pH$

the value of x, y, m and n are respectively

• A. 10, 2, 5, 2
• B. 2, 5, 2, 10
• C. 6, 4, 2, 4
• D. 3, 5, 2, 10

Answer 1

Answer: (B)

The balanced reaction is gives as

$2MnO_{4}^{-}+5H_{2}C_{2}O_{4}+6H^{+} \rightarrow 2Mn^{2 +}+10CO_{2}+8H_{2}O$

Thus, $x=2,y=5,m=2$ and $n=10$
