Assertion (A) Ferricyanide ion oxidises `H _(2) O _(2)` to `H _(2)O` in basic medium.
Reason ® Oxidation product of `H _(2) O _(2)` is ` O _(2),` Which of the following is true ?

Options

A. Both (A) and (R ) are true and (R ) is the correct explanation of (A)
B. Both (A) and (R ) are true, but (R ) is not correct
C. (A) is true, but (R ) is false
D. (A) is false, but (R ) is true

Answer

D

Explanation

In basic medium `H _(2) O _(2)` reacts as :
`H _(2)O_(2) + 2OH^(-) to 2H_(2) O + O_(2) +2e ^(-)`
In al/kaline medium `H _(2)O _(2)` reduces ferricyanide to ferrouscyanide as follows :
