Question

calculate the oxdiation number of kmno4​

Answer 1

Answer:

K=1 ,O= -8 Mn=7

Explanation:

Oxidation number of oxygen is -2 according to rule.

K has fixed oxidation number which is +1

According to rule sum of oxidation number of all elements is zero

So 1*1 + mn +4*-2=0

Mn=8-1=7

So Mn has oxidation number 7

Answer 2

Answer:

Explanation:

K=1 ,O= -8 Mn=7

Oxidation number of oxygen is -2

It has four atoms hence 4*-2=-8

K has oxidation number is +1

sum of oxidation number of all elements is zero

So 1*1 + Mn +4*-2=0

Mn oxidation =8-1=7

So Mn has oxidation number 7
