Error description

Q. Which has maximum number of equivalents per mole of the oxidant?

Redox Reactions

A

$I^{-} (aq) + IO^{-}_{3} (aq) \to I^{-}_{3} (aq)$

67%

B

$Ag(s) + NO_{3}^{-} (aq) \to NO_{2}(g) + Ag^{+} (aq)$

0%

C

$Mg(s) + VO_{4}^{3-} (aq) \to Mg^{2+} (aq) + V^{2+} (aq)$

33%

D

$Zn(s) + VO^{2+}+ (aq) \to V^{3+} (aq) + Zn^{2+} (aq)$

0%

Solution:

Oxidant is the oxidising agent (which has been reduced)

Change in ON Change in ON Equivalent per mol

a 1 1

b 1,2 1,2

c 2,5 2,5
