HI 3822 Sulfite Test Kit Analysis Method Sample Size Number of Tests Case Dimensions Shipping Weight · Place the syringe tip into the cap port of the plastic vessel and slowly add the titration solution dropwise, swirling to mix after each drop. Continue adding titration solution until the solution in the plastic vessel changes from colorless to blue. [. . . ] It will provide you with the necessary information for correct use of the kit. 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. Each kit is supplied with: · Sulfamic Acid Solution, 1 bottle with dropper (30 mL); · EDTA Reagent, 1 bottle with dropper (30 mL); · Sulphuric Acid solution, 1 bottle with dropper (15 mL); · Starch Indicator, 1 bottle with dropper (10 mL); · HI 3822-0 Reagent Titrant Solution, 1 bottle (120 mL); · 2 calibrated vessels (20 & 50 mL); · 1 calibrated syringe with tip. There are many reasons to monitor sulfite concentration in water. In industrial applications, a sulfite concentration of approximately 20 mg/L must be mantained to prevent pitting and oxidation of metal components as in boiler feed and effluent waters. A high level of sulfite results in a lowered pH, thus promoting corrosion. The monitoring of sulfite is important in environmental control. Sulfite ions are toxic to aquatic lifeforms and their ability to remove dissolved oxygen in water will destroy the delicate balance of ecology of lakes, rivers and ponds. The Hanna Sulfite Test Kit makes monitoring easy, quick and safe. The compact size gives the user the versatility to use the kit practically anywhere. The design of the kit makes it practically impossible to spill the reagents, thereby reducing the possibility of injury or damage to property. Note: mg/L is equivalent to ppm (parts per million). · Add 2 drops of Sulfuric Acid Solution through the cap port and mix as described before. x 20 = Na2SO3 · Add 1 drop of Starch Indicator through the cap port and mix.
