An azide is present to prevent any nitrite ions from interfering with the test. On addition of acid, manganese oxide hydroxide oxidizes the iodide to iodine. 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.\u003c\/p\u003e \u003cp\u003e\u003cbr\u003e \u003cstrong\u003eOrder information\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe HI-3810 test kit is supplied with the following; 30 mL manganous sulphate solution, 30 mL alkali-azide reagent, 60 mL sulphuric 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\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003eTitration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003e0.0-10.0 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSmallest Increment\u003c\/td\u003e\n\u003ctd\u003e0.1 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChemical Method\u003c\/td\u003e\n\u003ctd\u003eModified Winkler\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Tests\u003c\/td\u003e\n\u003ctd\u003eapprox. 110\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e910 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eDownloads\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/www.hannainstruments.co.uk\/modules\/teapotknowledgehub\/uploads\/3810-60db3c1b3cfda.pdf\" target=\"_blank\"\u003eHI-3810 Dissolved Oxygen Test Kit (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640059601269,"sku":"HI-3810","price":97.09,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/dissolved-oxygen-test-kit.jpg?v=1791580046","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-3810-dissolved-oxygen-test-kit","provider":"Test All Water","version":"1.0","type":"link"}
