Assertion : Conversion of potassium ferr...

Assertion : Conversion of potassium ferrocyanide to potassium ferricyanide is an oxidation process.
Reason : Oxidation is the addition of an electronegative element to a substance or removal of an electropositive element from a substance. : If both (A) and (R) are correct and (R) is the correct explanation of (A)., If both (A) and (R) are correct, but (R) is not the correct explanation of (A)., If (A) is correct, but (R) is incorrect., If both (A) and (R) are incorrect.

A

If both (A) and (R) are correct and (R) is the correct explanation of (A).

B

If both (A) and (R) are correct, but (R) is not the correct explanation of (A).

C

If (A) is correct, but (R) is incorrect.

D

If both (A) and (R) are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
A
`underset("Potassium ferrocyanide")(2K_4[Fe(CN)_6]_((aq))) + H_2O_(2(aq)) to underset("Potassium ferricyanide")(2K_3[Fe(CN)_6]_(aq)) + 2KOH`
The reaction is oxidation reaction due to removal of electropositive element (K) from potassium ferrocyanide to form potassium ferricyanide.
