Answer» Charge on Mn in MnO4– Charge on Oxygen is – 2 Mn + 4O= – 1 Mn +4(–2)= – 1 Mn= +7 So our reaction is MN7+àMn2+ n = 7– 2= 5 Required charge will= 5 × 96487 Coulombs = 482435 Coulombs = 4.82 × 105Coulombs

Answer»

Charge on Mn in MnO4–

Charge on Oxygen is – 2

Mn + 4O= – 1

Mn +4(–2)= – 1

Mn= +7

So our reaction is

MN7+àMn2+

n = 7– 2= 5

Required charge will= 5 × 96487 Coulombs

= 482435 Coulombs

= 4.82 × 105Coulombs
