SATHEE: Redox Reactions And Electrochemistry Ques 752

Redox Reactions And Electrochemistry Ques 752

Question: The pair of compounds in which both the metals are in the highest possible oxidation state is

Options:

A) ${[F e {(C N)}_{6}]}^{3 -},, {[C o {(C N)}_{6}]}^{3 -}$

B) $C r O_{2} C l_{2},, M n O_{4}^{-}$

C) $T i O_{3},, M n O_{2}$

D) ${[C o {(C N)}_{6}]}^{3 -},, M n O_{3}$

Show Answer

Answer:

Correct Answer: B

Solution:

[b] The sum of oxidation states of all atoms in a compound is equal to zero and sum of oxidation states of all atoms in an ion is equal to charge on the ion.

(i) ${[F e {(C N)}_{6}]}^{3 -},,$ O.N. of $F e = + 3,$ ${[C O {(C N)}_{6}]}^{3 -},$ O.N. of $C o = + 3$

(ii) $C r O_{2} C l_{2},$ O.N. of $C r = +, 6,$ ${[M n O_{4}]}^{-},$ O.N. of $M n = + 7$

(iii) $T i O_{3},,$ O.N. of $T i = + 6,$ $M n O_{2},$ O.N. of $M n = + 4$

(iv) ${[C o {(C N)}_{6}]}^{3 +},$ O.N. of $C o = + 3,$ $M n O_{3},$ O.N. of $M n = + 6$ .
