SATHEE: Redox Reactions And Electrochemistry Ques 668

Redox Reactions And Electrochemistry Ques 668

Question: In the disproportionation reaction $3 H C l O_{3} \overset{}{\to} H C l O_{4} + C l_{2} + 2 O_{2} + H_{2} O,$ the equivalent mass of the oxidizing agent is (molar mass of $H C l O_{3} = 84.45$ )

Options:

A) 16.89

B) 32.22

C) 84.45

D) 28.15

Show Answer

Answer:

Correct Answer: A

Solution:

[a] $C l O_{3}^{-} \overset{}{\to} C l_{2}^{0} x - 6 = - 1 x = 0 x = + 5 x = 0 (x = o x i d a t i o n n u m b e r)$ $E q u i v a l e n t m a s s = \frac{M o l e c u l a r m a s s}{O x i d a t i o n n u m b e r}$ $= \frac{84.45}{5} = 16.89$
