A) zero to \[+\,5\]
B) + 1 to + 5
C) zero to \[-\,3\]
D) + 2 to + 5
Correct Answer: A
Solution :
Bromine has zero oxidation state because it is in free state \[\overset{0}{\mathop{B{{r}_{2}}}}\,\xrightarrow{{}}BrO_{3}^{-}\] \[BrO_{3}^{-}\] \[x+(-2\times 3)=-1\] \[x+(-\,6)=-1\] \[x=+\,6-1\] \[=+\,5\] So, oxidation number changes from 0 to + 5.You need to login to perform this action.
