Question

(d) Oxidation number of Mn in K2 MnO4 is
(i) +4 (ii) +5 (iii) +6 (iv) +7​

Answer 1

Answer:

+6

Explanation:

2+X+(-8)=0

X=+6...

Answer 2

Answer:

+6

Explanation:

as oxidation number of K is +1

oxidation number of O is -2

since this salt having its total charge zero

thus,if we let the oxidation number number of Mn be 'x' then by putting total oxidation eqal to zero we get linear eqation in x :-

+1×2 + x -2×4 =0

by solving we get

X = +6

i.e. oxidation number of Mn.
