Redox Reactions And Electrochemistry Question 610
Question: Which of the following statements is not correct about the reaction given below- $ K_4[Fe{{(CN)}_6}]\xrightarrow{oxidation}F{{e}^{3+}}+CO_2+NO_3^{-} $
Options:
A) Fe is oxidised from $ F{{e}^{2+}} $ to $ F{{e}^{3+}}. $
B) Carbon is oxidised from $ {{C}^{2+}} $ to $ {{C}^{4+}} $ .
C) N is oxidised from $ {{N}^{3-}} $ to $ {{N}^{5+}} $ .
D) Carbon is not oxidised.
Show Answer
Answer:
Correct Answer: D
Solution:
[d] In $ C{{N}^{-}} $ , oxidation of C is +2, and it changes to +4 oxidation state in $ CO_2 $ . So C is also oxidised.
