Most common commercial forms are aqueous solutions containing about 6, 12 and 30 percent hydrogen peroxide and are referred to as “20-volume”, “40-volume” and “100-volume” respectively, meaning the value of oxygen liberated when the solution is boiled.\u003c\/p\u003e\n\u003cp\u003eIn the HI3844 test kit, hydrogen peroxide reacts slowly with iodide in acid solution (Step 1); thus a 15-minute interval is required to allow the reaction to occur completely. The amount of iodine generated is equivalent to the hydrogen peroxide in the sample. The liberated iodine is then titrated with standard sodium thiosulfate solution that reduces the iodine back to iodide ions (Step 2).\u003c\/p\u003e\n\u003ch5\u003eStep 1: H\u003csub\u003e2\u003c\/sub\u003eO\u003csub\u003e2\u003c\/sub\u003e + 2H\u003csup\u003e+\u003c\/sup\u003e + 2I\u003csup\u003e-\u003c\/sup\u003e → I\u003csub\u003e2\u003c\/sub\u003e + 2H\u003csub\u003e2\u003c\/sub\u003eO\u003c\/h5\u003e\n\u003ch5\u003eStep 2: I\u003csub\u003e2\u003c\/sub\u003e + 2(S\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\n\u003c\/h5\u003e\n\u003cp\u003eThe HI38444 is a convenient chemical test kit that is supplied complete with all the reagents and materials necessary to perform up to a 100 tests on average for hydrogen peroxide in swimming pools, spas, and hot tubs.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eHI38444\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003ePool Line Hydrogen Peroxide (as H2O2), Range: (0.25 mg\/L)(1.0 mg\/L) Method: titration, approx. 100 tests - HI38444\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHydrogen Peroxide Range\u003c\/td\u003e\n\u003ctd\u003e0.00 to 2.00 ppm H\u003csub\u003e2\u003c\/sub\u003eO\u003csub\u003e2\u003c\/sub\u003e; 0 to 10 ppm H\u003csub\u003e2\u003c\/sub\u003eO\u003csub\u003e2\u003c\/sub\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHydrogen Peroxide Resolution\u003c\/td\u003e\n\u003ctd\u003e0.25 ppm H\u003csub\u003e2\u003c\/sub\u003eO\u003csub\u003e2\u003c\/sub\u003e; 1 ppm H\u003csub\u003e2\u003c\/sub\u003eO\u003csub\u003e2\u003c\/sub\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHydrogen Peroxide Method\u003c\/td\u003e\n\u003ctd\u003eDrop-count iodometric titration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHydrogen Peroxide Number of Tests\u003c\/td\u003e\n\u003ctd\u003e100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e450 g (15.9 oz.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e0 to 50°C (32 to 122°F); RH max 95% non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eOrdering Info\u003c\/h3\u003e\u003cp\u003eHI38444 test kit is supplied with HI38444A-0 (100 mL) hydrogen peroxide reagent A, HI38444B-0 (17 g) hydrogen peroxide reagent B, HI38444C-0 (30 mL) hydrogen peroxide reagent C, starch indicator (25 mL), graduated plastic test tube with cap, calibration plastic vessel (50 mL), plastic pipette (3 mL), plastic pipette (1 mL), plastic spoon, and instruction manual.\u003c\/p\u003e\u003ch3\u003eManuals\u003c\/h3\u003e\u003cp\u003e\u003ca href=\"https:\/\/manuals.hannainst.com\/HI38444\" target=\"_blank\" rel=\"noopener\"\u003ePool Line Hydrogen Peroxide (as H2O2), Method: titration,100 tests - HI38444\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871459213681,"sku":"HI38444","price":9152.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/HI38441-scaled.jpg?v=1792646959","url":"https:\/\/hannainst.in\/products\/pool-line-hydrogen-peroxide-as-h2o2-method-titration-100-tests-hi38444","provider":"hanna","version":"1.0","type":"link"}
