Under neutral conditions water is dissociated into the (OH)- and H+ ions in equal ratio and hence it has a pH of 7. When bases or acids are added to a water solution they ionise, increasing the concentration of (OH)- or H+, respectively. Thus solutions with a pH of 1-3 contain strong acids, whereas those with a pH of 4-6 contain weak acids. \u003cbr\u003e\u003cbr\u003e Weak bases result in solutions of pH 8-10 and strong bases in pH of 11-13. \u003cbr\u003e\u003cbr\u003e \u003cb\u003eSupplied with\u003c\/b\u003e\u003cbr\u003e 30 mL pH 4.0-10.0 reagent Checker disc Glass vials with caps 3 mL plastic pipette \u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003eChecker Disc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003e4.0-10.0 pH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSmallest Increment\u003c\/td\u003e\n\u003ctd\u003e0.5 pH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChemical Method\u003c\/td\u003e\n\u003ctd\u003epH indicator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber 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\u003e215 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\/manhi_38058-60db2afac0ffc.pdf\" target=\"_blank\"\u003eHI-38058 pH Test Kit (PDF)\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":57640059371893,"sku":"HI-38058","price":105.92,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/5511\/6439\/files\/ph-range-4-0-10-0-ph.jpg?v=1791580035","url":"https:\/\/testallwater.co.uk\/products\/hanna-instruments-hi-38058-ph-test-kit-range-4-0-10-0-ph","provider":"Test All Water","version":"1.0","type":"link"}
