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.
