Redox Reactions And Electrochemistry Ques 599
Question: Small quantities of solutions of compounds TX, TY and TZ are put into separate test tubes containing X, Y and Z solution. TX does not react with any of these. TY reacts with both X and Z. TZ reacts with X. The decreasing order of state of oxidation of the anions $ {X^{-}},{Y^{-}},{Z^{-}} $ is
Options:
A) $ {Y^{-}},{Z^{-}},{X^{-}} $
B) $ {Z^{-}},{X^{-}},{Y^{-}} $
C) $ {Y^{-}},{X^{-}},{Z^{-}} $
D) $ {X^{-}},{Z^{-}},{Y^{-}} $
Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ Oxidisingtendency\propto \frac{1}{Electrodepotential} $ $ TX\xrightarrow{{}}Noreaction $ $ TY\xrightarrow{{}}X,Z $ $ TZ\xrightarrow{{}}X $
$ \Rightarrow $ order of electrode potential is $ TY<TZ<TX $
$ \Rightarrow $ Order of oxidation of the anion is $ {Y^{-}}>{Z^{-}}>{X^{-}} $
