The HI3822-100 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate alkalinity measurements with the chemical test kit. These reagents follow an iodometric titration method to determine sulfite concentration.
For determination of sulfite, iodine formed in the presence of sulfuric acid reacts with sulfite to form iodide. As the solution is titrated, an excess of iodine is generated which forms a blue color complex. The number of drops of titrant used to reach the visual endpoint will determine the sulfite as mg/L Na2SO3. These reagents are designed to be used with samples that have an expected sulfite range of 0.0 to 20.0 mg/L and 0 to 200 mg/L Na2SO3.
