Identify the ionic charge and magnetic nature respectively of manganate ion.
Identify the ionic charge and magnetic nature respectively of manganate ion.
-1, Diamagnetic
-2, Diamagnetic
-2, Paramagnetic
-1, Paramagnetic
Solution
Manganate ion is paramagnetic due to presence of unpaired electron. Chemical formula for manganate and permanganate ion respectively are Mn2-4 and mnO-4. Thus, the ionic charge of manganate and permangante ion are respectively -2 and -1.25-
