Let the molecular weight of KBrO₃ be 'M'.


Oxidation state of Br in BrO₃⁻ :

x + 3(-2) = -1

x - 6 = -1

x = +5


Oxidation state of Br in Br⁻ :

x = -1


Thus, the oxidation state of Br in the given reaction, changes from +5 to -1.


→ n-factor = change in oxidation state = 5 - (-1) = 6


Therefore Equivalent weight of KBrO₃ = M/n-factor = M/6


Hope it helps!!
