Question

For the redox reaction MnO4– + C2O42– + H+$\longrightarrow$Mn2+ + CO2 + H2O,

• A. 2, 5, 16
• B. 16, 5, 2
• C. 5, 16, 2
• D. 2, 16, 5

Answer 1

Answer: (A)

2, 5, 16

Answer 2

(1)

MnO4– + C2O42– + H+$\longrightarrow$ Mn2+ + CO2 + H2O

V.f. = 5 V.f. = 2

$\therefore$ Balanced equation : 2MnO4– + 5C2O42– + 16H+

$\longrightarrow$2Mn2+ + 10CO2 + 8H2O
