Question

what is the oxidation number of manganese in MnO4-

Answer 1

LET OXIDATION NUMBER OF MANGENESE be x.

And overall charge is - 1.

So,

x + 4 ( -2 ) = - 1

x - 8 = - 1

x = - 1 + 8

x = + 7

✔️ OXIDATION NUMBER OF MANGENESE is.....

⏺️+ 7.

Answer 2

★Here's the required answer★

MnO4-

x + 4 (-2) = -1

x - 8 = -1

x = -1+8

x = +7

Oxidation number of manganese is 7

★Hope this helps★

Have a great day ^_^
