Answer 2

Answer: 6 faradays are required to reduce 1 mole of BrO_3^- to Br^-

Explanation: 1 faraday means 1 mole of electrons.

For the reduction of BrO_3^- to Br^-, the equation follows:

BrO_3^-(aq)+6H^+(aq)+6e^-\rightarrow Br^-(aq)+3H_2O(l)

Oxidation state of Bromine at Reactant side = +5

Oxidation state of Bromine at Product side = -1

So, to obtain the oxidation state of bromine -1, we require 6 electrons and hence, 6 faradays is required to 1 mole of BrO_3^- to Br^-
