Redox Reactions And Electrochemistry Ques 187
Question: $ KMnO_4 $ acts as an oxidising agent in the neutral medium and gets reduced to $ MnO_2 $ . The equivalent weight of $ KMnO_4 $ in neutral medium [AMU 2001]
Options:
A) mol. wt/2
B) mol.wt/3
C) mol. wt/4
D) mol .wt/7
Show Answer
Answer:
Correct Answer: B
Solution:
In an neutral medium $Mn^{7+}$ changes to $Mn^{4+}$.There is an 3 electron transfer during $ KMnO_4 $ reaction in neutral medium.Equivalent weight will be M/3 .
