These reagents follow the Alizarin Yellow R method to determine formaldehyde concentration.\u003c\/p\u003e\n\u003cp\u003eFor formaldehyde determination,  dilute hydrochloric acid is used as the titrant. Alizarin Yellow R reagent is used to form a red-orange color complex for visual indication. Sodium sulfite reagent is used to form an alkaline formaldehyde product. Dropwise addition of the acidic titrant causes the solution to turn from red-orange to yellow as it reaches the Alizarin Yellow R endpoint. The number of milliliters of titrant used to reach the endpoint will determine the formaldehyde concentration as mg\/L CH\u003csub\u003e2\u003c\/sub\u003eO. These reagents are designed to be used with samples that have an expected formaldehyde range of 0.0 to 1.0 % and 0 to 10% Formaldehyde (CH\u003csub\u003e2\u003c\/sub\u003eO).\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e HI3838-100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e Formaldehyde Chemical Test Kit Replacement Reagents (110 tests) -  HI3838-100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003e bottles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e 110 tests\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003e Alizarin Yellow R\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\/HI3838-100\"\u003eFormaldehyde Chemical Test Kit Replacement Reagents (110 tests) - HI3838-100\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871269650801,"sku":"HI3838-100","price":6911.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/hi3838-100_1.jpg?v=1792646003","url":"https:\/\/hannainst.in\/products\/formaldehyde-chemical-test-kit-replacement-reagents-110-tests-hi3838-100","provider":"hanna","version":"1.0","type":"link"}
