In oceans,  lakes,  rivers,  and other surface water bodies,  dissolved oxygen is essential to the growth and development of aquatic life. Without oxygen,  water can become toxic due to the anaerobic decaying of organic matter. In man’s environment,  water must contain at least 2 mg\/L of oxygen to protect water pipes from corrosion. However,  boiler system water,  in many cases,  cannot contain greater than 10 mg\/L oxygen.\u003c\/p\u003e\n\u003cp\u003eA modified Winkler method is used in the HI3810 test kit. Manganous ions react with oxygen in the presence of potassium hydroxide to form a manganese oxide precipitate (Step 1). An azide is present to prevent any nitrite ions from interfering with the test. With addition of acid,  manganese oxide hydroxide oxidizes the iodide to iodine (Step 2). Since the amount of iodine generated is equivalent to the oxygen in the sample,  the concentration of iodine is calculated by titration of thiosulfate ions that reduce the iodine back to iodide ions (Step 3).\u003c\/p\u003e\n\u003cp\u003eStep 1: 2Mn\u003csup\u003e2+\u003c\/sup\u003e + O\u003csub\u003e2\u003c\/sub\u003e + 4OH\u003csup\u003e-\u003c\/sup\u003e → 2MnO(OH)\u003csub\u003e2\u003c\/sub\u003e\u003c\/p\u003e\n\u003cp\u003eStep 2: MnO(OH)\u003csub\u003e2\u003c\/sub\u003e + 2I\u003csup\u003e-\u003c\/sup\u003e + 4H\u003csup\u003e+\u003c\/sup\u003e → Mn\u003csup\u003e2+\u003c\/sup\u003e + I\u003csub\u003e2\u003c\/sub\u003e + 3H\u003csub\u003e2\u003c\/sub\u003eO\u003c\/p\u003e\n\u003cp\u003eStep 3: I\u003csub\u003e2\u003c\/sub\u003e + 2S\u003csub\u003e2\u003c\/sub\u003eO\u003csub\u003e3\u003c\/sub\u003e\u003csup\u003e2-\u003c\/sup\u003e → 2I\u003csup\u003e-\u003c\/sup\u003e + S\u003csub\u003e4\u003c\/sub\u003eO\u003csub\u003e6\u003c\/sub\u003e\u003csup\u003e2-\u003c\/sup\u003e\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e HI3810\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e Dissolved Oxygen Chemical Test Kit - HI3810\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDissolved Oxygen Measurement Type\u003c\/td\u003e\n\u003ctd\u003e Titration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDissolved Oxygen Range\u003c\/td\u003e\n\u003ctd\u003e 0.0 to 10.0 mg\/L O₂\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDissolved Oxygen Resolution\u003c\/td\u003e\n\u003ctd\u003e 0.1 m\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDissolved Oxygen Measurement Method\u003c\/td\u003e\n\u003ctd\u003e modified Winkler\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDissolved Oxygen Number of Test\u003c\/td\u003e\n\u003ctd\u003e 110\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e 910 g (34.0 oz.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e 260x120x60 mm (10.2x4.7x2.4 in.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eOrdering Info\u003c\/h3\u003e\u003cp\u003eHI3810 test kit comes with 30 mL manganous sulfate solution, 30 mL alkali-azide reagent, 60 mL sulfuric acid solution (2), 10 mL starch indicator, 120 mL titrant solution, glass bottle with stopper, 10 mL calibrated vessel, and calibrated syringe with tip.\u003c\/p\u003e\u003ch3\u003eManuals\u003c\/h3\u003e\u003cp\u003e\u003ca target=\"_blank\" href=\"https:\/\/manuals.hannainst.com\/HI3810\"\u003eDissolved Oxygen Chemical Test Kit - HI3810\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871256641905,"sku":"HI3810","price":9631.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/hi3810.jpg?v=1792645972","url":"https:\/\/hannainst.in\/products\/dissolved-oxygen-chemical-test-kit-hi3810","provider":"hanna","version":"1.0","type":"link"}
