The adjustment of the wine sample with 5 mL of the acidic reagent ensures the sample is at the correct pH. The addition of HI84500-62 stabilizing powder is also added prior to performing the titration. The HI3148B ORP electrode is used to detect the endpoint for both the low (1.0 to 40.0 ppm of SO\u003csub\u003e2\u003c\/sub\u003e) and high (30 to 400 ppm of SO\u003csub\u003e2\u003c\/sub\u003e) ranges. The HI84500 can be used with all wines,  including red,  which are difficult to test using traditional methods due to the difficulty to observe a distinctive color change when the endpoint is reached.\u003c\/p\u003e\n\u003cp\u003eThe HI84500 determines the free and total sulfur dioxide concentration in wine using the Ripper method. Excess iodide is added to the wine sample and reacts with the iodate titrant to produce iodine:\u003c\/p\u003e\n\u003ch5\u003eIO\u003csub\u003e3\u003c\/sub\u003e\u003csup\u003e-\u003c\/sup\u003e + 5I\u003csup\u003e-\u003c\/sup\u003e + 6H\u003csup\u003e+\u003c\/sup\u003e → 3I\u003csub\u003e2\u003c\/sub\u003e + 3H\u003csub\u003e2\u003c\/sub\u003eO\u003c\/h5\u003e\n\u003cp\u003eThe iodine produced reacts with sulfur dioxide in the wine according to the redox reaction below:\u003c\/p\u003e\n\u003ch5\u003eH\u003csub\u003e2\u003c\/sub\u003eSO\u003csub\u003e3\u003c\/sub\u003e + I\u003csub\u003e2\u003c\/sub\u003e → H\u003csub\u003e2\u003c\/sub\u003eSO\u003csub\u003e4\u003c\/sub\u003e + 2HI\u003c\/h5\u003e\n\u003cp\u003eReplacement reagents required to operate the HI84500 include:\u003c\/p\u003e\n\u003cdiv style=\"overflow-x: auto; margin: 0 0 32px;\"\u003e\u003ctable\u003e\n\u003ccolgroup\u003e\n\u003ccol width=\"200\"\u003e\n\u003ccol width=\"300\"\u003e\n\u003ccol width=\"300\"\u003e\n\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003e\u003cstrong\u003eLow Range - 1.0 to 40.0 ppm of SO\u003csub\u003e2\u003c\/sub\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003e\u003cstrong\u003eHigh Range - 30 to 400 ppm of SO\u003csub\u003e2\u003c\/sub\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cp\u003ePump calibration standard\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84500-55\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84500-55\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cp\u003eTitrant solution\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84500-50\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84500-51\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cp\u003eAcid reagent\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84500-60\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84500-60\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cp\u003eAlkaline reagent (Total SO\u003csub\u003e2\u003c\/sub\u003e)\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84500-61\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84500-61\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cp\u003eStabilizer powder packets\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84500-62\u003c\/p\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cp\u003eHI84500-62\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e HI84500-60\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e Acid Reagent for Free and Total Sulfur Dioxide - HI84500-60\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription\u003c\/td\u003e\n\u003ctd\u003e Acid Reagent for Free and Total Sulfur Dioxide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003e bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e 1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize\u003c\/td\u003e\n\u003ctd\u003e 230 mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eManuals\u003c\/h3\u003e\u003cp\u003e\u003ca target=\"_blank\" href=\"https:\/\/manuals.hannainst.com\/HI84500-60\"\u003eAcid Reagent for Free and Total Sulfur Dioxide - HI84500-60\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871417008497,"sku":"HI84500-60","price":2863.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/untitled_3_1.jpg?v=1792646573","url":"https:\/\/hannainst.in\/products\/acid-reagent-for-free-and-total-sulfur-dioxide-hi84500-60","provider":"hanna","version":"1.0","type":"link"}
