Redox Reactions And Electrochemistry Ques 668
Question: In the disproportionation reaction $ 3HClO_3\xrightarrow{{}}HClO_4+Cl_2+2O_2+H_2O, $ the equivalent mass of the oxidizing agent is (molar mass of $ HClO_3=84.45 $ )
Options:
A) 16.89
B) 32.22
C) 84.45
D) 28.15
Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ ClO_3^{-}\xrightarrow{{}}Cl_2^{0} \\ x-6=-1 x=0 \\ \\ x=+5 x=0( x=oxidationnumber ) \\ \\ \\ $ $ Equivalentmass=\frac{Molecularmass}{Oxidationnumber} $ $ =\frac{84.45}{5}=16.89 $
