Webb19 jan. 2024 · Use of stannated Hydrochloric acid: If pure zinc and HCl are used, the steady evolution of gas does not occur. This produces improper stain (e.g slow evolution produces short but intense stain while rapid evolution of gas produces long but diffused stain.) So, to get steady evolution of gas, stannated hydrochloric acid is used. WebbProcedure Test solution: • The test solution is prepared by dissolving specificamount in water and stannated HCl (arsenic free) and kept in a wide mouthed bottle. • To this solution 1 gm of KI, 5 ml of stannous chloride acid solution and 10 gm of zinc is added (all this reagents must be arsenic free).
