Question

MnO42– (1 mole) in neutral aqueous medium is disproportionate to :-
(1) 2/3 mole of MnO4– and 1/3 mole of MnO2
(2) 1/3 mole of MnO4– and 2/3 mole of MnO2
(3) 1/3 mole of Mn2O7 and 1/3 mole of MnO2
(4) 2/3 mole of Mn2O7 and 1/3 mole of MnO2

Answer 1

Answer:

Explanation:

Correct option  (a) 2/3 mole of MnO4- and 1/3 mole of MnO2 E

Answer 2

Answer:

The correct answer to this question is 2/3 mole of  $MnO^{-} _{4}$and 1/3 mole of $MnO_{2}$

Explanation:

Given - MnO42– (1 mole) in a neutral aqueous medium.

To Find - Choose the correct option.

$MnO^{2-} _{4}$ (1 mole) in neutral aqueous medium is disproportionate to  

2/3 mole of $MnO^{-} _{4}$ and 1/3 mole of $MnO_{2}$

$3K_{2}MnO_{4} +2H_{2}O$ →$2KMnO_{4} + MnO_{2}+4KOH$

Neutral aqueous solutions are pH-balanced combinations of water and other chemical substances. Surfactants, corrosion inhibitors, and other additives are examples of chemical substances. The most widely utilized aqueous solutions are neutral and alkaline aqueous solutions.
