Minititrator Reagents 

The HI84531-50 is a 120 mL bottle of acidic titrant solution that is used for low range (30 to 400 mg/L as CaCO3) determination of alkalinity in water.

Water alkalinity is an expression of a water’s acid-neutralizing capacity and it is determined by titration with standard acidic solutions. Alkalinity is an important parameter for control and treatment of potable water and wastewater because it indicates the buffering capacity of water, or the ability to resist a pH change. The ability to resist large swings in pH results primarily from the presence of bicarbonates and carbonates. A low water alkalinity signifies that the water is susceptible to pH change, while a high alkalinity indicates that water is able to resist a major change of pH.
