(i) What is the weight of sodium bromate and molarity pf solution necessary to prepare 85.5 ml of 0.672 B solution when the half-cell reaction is
$$BrO_3^- + 6H^+ + 6e^- \to $$ $$Br^- + 3H_2O$$
(ii) What would be the weight as well as molarity if the half-cell reaction is:
$$2BrO_3^- + 12H^+ + 10e^- \to$$ $$Br_2 \,+ 6H_2O$$
$$BrO_3^- + 6H^+ + 6e^- \to $$ $$Br^- + 3H_2O$$
(ii) What would be the weight as well as molarity if the half-cell reaction is:
$$2BrO_3^- + 12H^+ + 10e^- \to$$ $$Br_2 \,+ 6H_2O$$
