Alkaline Reagent for Total Sulfur Dioxide – HI84100-51

The HI84100-51 is a 500 mL bottle of alkaline reagent required for determination of total sulfur dioxide in wine using the HI84100 Sulfur Dioxide Mini Titrator for Wine Analysis.*This alkaline reagent is used to raise the pH value of the sample prior to performing a titration. With 5 mL of reagent required per test, there is enough alkaline reagent for 100 tests.

*The HI84100 Sulfur Dioxide Mini Titrator has been discontinued. The new version is the HI84500 Sulfur Dioxide Mini Titrator for Wine Analysis which has its own set of reagents.

  • Pre-measured solution
  • Clearly marked expiration date and lot number

The HI84100-51 alkaline reagent is necessary for the analysis of total sulfur dioxide. The alkaline reagent raises the pH and liberates bound sulfur dioxide. This pH adjustment ensures that all of the free and bound sulfur dioxide is accounted for to give an accurate measurement of total sulfur dioxide. The HI3148B ORP electrode is used to detect the endpoint. The HI84100 can be used with all wines, including red, which are difficult to test using traditional methods due to the difficulty to observe a distinctive color change when the endpoint is reached.The HI84100 Sulfur Dioxide Mini Titrator determines the free and total sulfur dioxide concentration in wine using the Ripper method. Excess iodide is added to the wine sample and reacts with the iodate titrant to produce iodine:IO3– + 5I– + 6H+ → 3I2 + 3H2OThe iodine produced reacts with sulfur dioxide in the wine according to the redox reaction below:H2SO3 + I2 → H2SO4 + 2HIReplacement reagents required to operate the HI84100 include:
