2Cr + 7O = -2
2Cr + 7(-2) = -2
2Cr = 12
Cr =+6
Cr⁶⁺ + 3e => Cr³⁺ , reduksi / oksidator
b. ClO3 ==> Cl-
Cl + 3(-2) = 0
Cl=+6
Cl⁶⁺ + 7e => Cl- , reduksi / oksidator
c. P2O5 ==> PO4³⁻ ,
2P + 5(-2) = 0
2P = 10
P=+5
P + 4(-2) = -3
P=+5 , tidak mengalami perubahan biloks
d. IO3- ==> I-
I + 3(-2) = -1
I =+5
I⁵⁺ + 6e => I- reduksi / oksidator
e. S²⁻ ==> S
S =0
S²⁻ => S + 2e oksidasi / reduktor
jawabannya a. Cr2O7²⁻ ==> Cr³⁺
