It is the titrant used to run a total alkalinity test.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAlkalinity is measured by counting the drops of acid it takes to bring a sample to its endpoint. The strength of the acid is what makes each drop mean a fixed number of parts per million, which is why the .12N figure matters and why a substitute of a different strength gives the wrong answer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBuy the bottle, not the kit\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eReagents run out at different rates, so a single refill bottle is usually all that is needed. Taylor advises replacing reagents about once a year regardless of how much is left, because chemistry that has sat for a long time quietly stops reading true.\u003c\/p\u003e","brand":"Taylor Technologies","offers":[{"title":"Default Title","offer_id":48635038990548,"sku":"TAY-45-1007","price":11.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_cc13d6c5-db90-44ea-833a-9b48b25604a0.jpg?v=1788840342","url":"https:\/\/www.activepoolsupply.com\/products\/sulfuric-acid-12n-75-oz-dropper-bottle","provider":"Active Pool Supply","version":"1.0","type":"link"}
