Question

KMnO4 in alkaline medium changes to (A) Mn3+ (B) MnO2 (C) MnO42- (D) Mn(OH)4-

Tardigrade Admin · Accepted Answer

In alkaline solution, KMnO4 is first reduced to manganate and then to insoluble manganese dioxide. 2KMnO4 + H2O xrightarrow textalkaline 2MnO2 + 2KOH + 3[O]

Q. $K M n O_{4}$ in alkaline medium changes to

$M n^{3 +}$

$M n O_{2}$

$M n O_{4}^{2 -}$

$M n (O H)_{4}^{-}$

In alkaline solution, $K M n O_{4}$ is first reduced to manganate and then to insoluble manganese dioxide.
$2 K M n O_{4} + H_{2} O alkaline 2 M n O_{2} + 2 K O H + 3 [O]$
