Chemistry - Stoichiometry Question with Solution | TestHub

Chile saltpeter, a source of NaNO₃, also contains NaIO₃. The NaIO₃ can be used as a source of iodine, produced in the following reactions: IO₃⁻ + 3HSO₃⁻ $\to$ I⁻ + 3H⁺ + 3SO₄²⁻ and 5I⁻ + IO₃⁻ + 6H⁺ $\to$ 3I₂ + 3H₂O. One litre of Chile saltpeter solution containing 5.94 g NaIO₃ is treated with stoichiometric quantity of NaHSO₃. Now an additional amount of same solution is added to the reaction mixture to bring about the second reaction. (I = 127)
