Question

Oxidation number of Cl in HClO3

Answer 1

oxidation of H is +1

oxidation of O is -2=-8

+1+x-8=0

x=8-1

x=7

HOPE ITS HELPFULL...

Answer 2

Explanation:

here

H ---> +1

O ----> -2. 3×O = -6

total negative charge = -6

let charge on Cl = x

x + 1 - 6 = 0

x = +5

so the charge on Cl is +5.
