The ionic charges of manganate and permanganate ion are respectively

A

`-2,-2`

B

`-1,-2`

C

`-2,-1`

D

`-1,-1`

Text Solution

Verified by Experts

The correct Answer is:
C
Chemical formula for manganate and permanganate ion respectively are `Mn_(4)^(2-)` and `mnO_(4)^(-)`. Thus, the ionic charge of manganate and permangante ion are respectively -2 and -1.
