Taylor’s Alkalinity Test KitsINTRODUCTIONAlkalinity is the acid-neutralizingcapacity of water. Althoughmany bases (such as borates, phosphates,and silicates) contribute to awater’s alkalinity, it is primarily afunction of the carbonate, bicarbonate,and hydroxide concentrations. Alkalinitycontrol is important in manyprocesses including municipal waterand wastewater treatment, paper andtextile manufacturing, commerciallaundering, warewashing, beverageproduction, and boiler and coolingsystem operation.Alkalinity is determined by titrationwith a standard acid to a designatedpH and recorded as either P, M, or Talkalinity. P alkalinity is titrated to anendpoint pH of 8.3 using phenolphthaleinas the indicator, M alkalinity istitrated to an endpoint pH of 4.6 usingmethyl orange as the indicator, andT alkalinity is titrated to an endpointpH of 4.5 using a blended indicator(bromocresol green/methyl red). Ifsulfuric acid is being added to modifypH, it will also alter the P/T alkalinityrelationship.Note: Reagent packs for burettitration setups contain chemicals andinstructions only.ALKALINITY KITSK-1512Drop test (laundry test using H 2SO 4);1 drop = 10 or 50 ppm P/T alkalinityas CaCO 3K-1527Drop test (using H 2SO 4);1 drop = 10 ppm P/T alkalinityas CaCO 3K-1528Drop test (using HCl);1 drop = 0.2 g/100 mL caustic alkalinityas NaOH;1 drop = 0.256 g/100 mL total alkalinityas Na 2CO 3K-1530Drop test (using H 2SO 4);1 drop = 10 ppm total alkalinityas CaCO 3Taylor's K-1533PM will perform 140 tests for P/M alkalinity at 100 ppm.K-1531Drop test (using H 2SO 4) for caustic soda;1 drop = 0.1 or 1% caustic alkalinityas NaOHK-1533PMDrop test (using H 2SO 4);1 drop = 10 or 50 ppm P/M alkalinityas CaCO 3K-1533PTDrop test (using H 2SO 4);1 drop = 10 or 50 ppm P/T alkalinityas CaCO 3K-1537Drop test (using HCl);1 drop = 10 or 50 ppmhydroxyl alkalinity as CaCO 3K-1542 (combination kit)Drop tests for PET bottlers measuringM alkalinity (using HCl);1 drop = 10 ppm CaCO 3;total hardness* (EDTA titration);1 drop = 10 ppm CaCO 3K-1575Drop test (using HCl);1 drop = 10 or 50 ppm P/Mor P/T alkalinity as CaCO 3K-0430Buret titration reagent pack(using H 2SO 4);1 mL = 1 mg P/M or P/T alkalinityas CaCO 3K-0431Buret titration reagent pack(using H 2SO 4);1 mL = 5 mg P/M or P/T alkalinityas CaCO 3*includes inhibitors to prevent metalinterferenceUSER BENEFITS•Titrations do not require the abilityto match colors, only the ability to seethe permanent color change at the•endpoint of the reaction.Drop-test kits are practical for both•on- and off-site testing.Buret titrations provide laboratory•accuracy at an economical price.Waterproof instructions areprinted on plastic-impregnated paper•that resists fading and tearing.Color coding of reagent caps to•instructions helps prevent mishaps.Picture guides to color transitions•in the test reassure new users.Custom-molded, durable plastic•cases provide safe storage for all tests.Proven chemistries are based onStandard Methods for the Examinationof Water and Wastewater, APHA,Washington, DC, and/or AmericanSociety for Testing and Materials,ASTM, Philadelphia, PA. Somemethods use proprietary chemistrydeveloped by Taylor Technologies.
