Published on: August 13, 2026

Consider the following statements about manganate and permanganate ions. Identify the correct statements.

The geometry of both manganate and permanganate ions is tetrahedral.
and

The oxidation states of Mn in manganate and permanganate are +7 and +6 , respectively.
and

Oxidation of Mn (II) salt by peroxodisulphate gives manganate ion as the final product.
and Only

Manganate ion is paramagnetic and permanganate ions is diamagnetic.
(E) Acidified permanganate ion reduces oxalate, nitrite and iodide ions. Choose the correct answer from the options given below:
Only Only
and (E) Only

Text Solution

Verified by Experts

The correct answer is:

Manganate ion

Permanganate ion
Both are tetrahedral ( hybridisation) TRUE
has Mn in +7 oxidation state; has Mn in +6 oxidation state. The statement says +7 for manganate and +6 for permanganate, which is reversed. FALSE
Oxidation of by peroxodisulphate gives permanganate ion , not manganate ion. FALSE
is diamagnetic; is paramagnetic. TRUE
(E) Acidified permanganate ion oxidises (not reduces) oxalate, nitrite and iodide ions. FALSE
