Explanation:
:
Ferrous ion
is oxidized:
F
e
2
+
→
F
e

e
−
(
i
)
And
permanganate ion
is reduced:
M
n
O
−
4

8
H

5
e

→
M

For each half-equation charge and mass are balanced ABSOLUTELY, and thus it reflects stoichiometry. TO produce a balanced equation, we adds
(
i
)
and
(
i
i
)
in such a way as to remove the electrons as virtual particles of convenience...
i.e.
5

(

(

gives....

The which is balanced with respect to mass and charge....and note that the colour change of the reaction, deep-purple permanganate to almost colourless

, would give us a visual gauge on the extent of reaction.
