What would happen if Mno2 was mixed with KI and 9 M sulfuric acid? b. What would happen if Mno2 was mixed with KBrO3 and 9 M sulfuric acid?

Explanation / Answer

1)
a)Br2O=Br=+1
So in this state is -2

b)Hcl03=Cl=+1 or -7

H+1

O=-2

So therefor Cl=-7

c)BrO2

n (BrO2)-

let the oxidation no of Br be x
then we know the oxidation number of O which is -2
then x+2(-2)=-1
x=3.

d)Cl2=0

e)HClO2=(+1) + (Cl) + (-4) = 0

(Cl) + (-3) = 0
(Cl) = +3

f)KI=K=+1 I=-1

g)H5IO6=H5IO6: +7

h)Cl0-=CL+1
