These reagents follow the methyl orange\/phenolphthalein method to determine strong acid\/total acid concentration.\u003c\/p\u003e\n\u003cp\u003eFor strong acid determination,  also known as methyl orange acidity,  the sodium hydroxide titrant reacts with acids present in the sample. With addition of bromophenol blue indicator,  the solution turns from yellow to green\/blue as it reaches the pH endpoint near pH 4.5. For total acid determination,  also known as phenolphthalein acidity,  sodium hydroxide is also used as the titrant. With addition of phenolphthalein indicator,  the solution turns pink as it reaches the pH endpoint near pH 8.3. The number of milliliters of titrant used to reach the appropriate endpoint will determine the acidity as mg\/L CaCO\u003csub\u003e3\u003c\/sub\u003e. These reagents are designed to be used with samples that have an expected acidity range of 0 to 100 mg\/L and 0 to 500 mg\/L CaCO\u003csub\u003e3\u003c\/sub\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 HI3820-100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eName\u003c\/td\u003e\n\u003ctd\u003e Acidity Chemical Test Kit Replacement Reagents (100 tests) - HI3820-100\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 100 tests\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003e methyl orange \/ phenolphthalein\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\/HI3820-100\"\u003eAcidity Chemical Test Kit Replacement Reagents (100 tests) - HI3820-100\u003c\/a\u003e\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":67871261884785,"sku":"HI3820-100","price":5469.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/hi3820-100.jpg?v=1792645982","url":"https:\/\/hannainst.in\/products\/acidity-chemical-test-kit-replacement-reagents-100-tests-hi3820-100","provider":"hanna","version":"1.0","type":"link"}
