Question

Oxidation states of V and Br in V(BrO2)2

Answer 1

hi u r answer is here

when it combines with non-metals the oxidation number is (+1)

when it combines with metals the oxidation number is (-1)

Answer 2

The oxidation number of V = + 2 and the oxidation number of BR = + 3.

Explanation:

The given compound

$V(BrO_{2})_{2}$

Find Oxidation states of V and Br.

Find Br,

$(+ 2) +(Br(-2)_{2})_{2}=0$

⇒ $2+2Br-8=0$

⇒ $2Br=6$

∴ Br = + 3

Find V,

$V +((+3)+(-2)_{2})_{2}=0$

⇒$v+((+3)+2(-2))\times 2=0$

⇒ V = +2

Hence, the oxidation number of V = + 2 and the oxidation number of BR = + 3.
