Rinse the plastic vessel with water sample, fill to the 5 mL 5 mL mark and replace the cap. [. . . ] This measurement is very important in determining the corrosive characteristics of water due primarily to hydroxide, carbonate and bicarbonate ions. Other sources of alkalinity can be from anions that can be hydrolyzed such as phosphate, silicate, borate, fluoride and salts of some organic acids. Alkalinity is critical in the treatments of drinking water, wastewater, boiler & cooling systems. The Hanna Alkalinity Test Kit makes monitoring easy and quick. The compact size gives the user the versatility to use the kit anywhere. The design makes the kit easy to handle. Note: 1 gpg (grains per gallon) CaCO3 is equivalent to 17 ppm CaCO3 (where ppm - parts per million - is equivalent to mg/L). x1 Note: Any damaged or defective item must be returned in its original packing materials. ISTR38014 11/00 Dear Customer, Thank you for choosing a Hanna Product. SPECIFICATIONS Please read the instruction sheet carefully before using the test kit. It will provide you with the necessary information for correct use of the kit. If you need additional information, do not hesitate to e-mail us at tech@hannainst. com. Remove the chemical test kit from the packing material and examine it carefully to make sure that no damage has occurred during shipping. If there is any noticeable damage, notify your Dealer or the nearest Hanna office immediately. [. . . ] Read the relevant Health and Safety Data Sheets before performing the test. CHEMICAL REACTION Total Alkalinity is determined by neutralizing the sample to a pH of 4. 5 using a dilute sulfuric acid solution and a bromophenol blue indicator. This process converts hydroxide ions to water, carbonate and bicarbonate ions to carbonic acid: ­ ­ 2OH +H2SO4 2H2O+SO42 ­ ­ ­ 2CO2 +H2SO4 2HCO3 +SO42 3 ­ 2HCO3 +H2SO4 2H2CO3+SO42­ PRINTED IN ITALY [. . . ]
