Sulfite (Sodium)Buret TitrationIodometric1 mL = 1 mg Na2SO3NANA

In buret titrations, a solution of known concentration is added gradually from a buret to either a solution of a weighed quantity of unknown material or to a precisely known volume of solution of the unknown material. Addition is continued until the exact mole ratio required by the balanced chemical equation is reached. This point is called the “equivalence point” of the titration and is usually detected through the addition of an indicator to the solution being titrated.

Because it readily reacts with oxygen to form sulfate, sulfite is not usually found in natural water systems. In its most common form, sodium sulfite, it is widely used as an oxygen scavenger in feedwater conditioning to prevent pitting in boilers; as a pulping or pulp-bleaching agent by the paper industry; to neutralize residual chlorine in potable water, sewage, industrial effluents, and textile process waters; and as a reducing agent in still other manufacturing processes.

Sample water over 100°F will cause a false-high reading; therefore, quickly cool to room temperature before testing. To prevent a false-low reading caused by the reaction between sulfite and ambient air or dissolved oxygen, water samples should be capped while cooling and then tested without delay. An iodometric drop test is the most popular field method for determining sodium sulfite concentrations.

Note: Sulfide and ferrous iron cause positive interference; copper and nitrite cause negative interference.
