Prices include GST. Not all items are in stock. Call 03 9769 0666 to confirm.

The HI84100-52 is a 500 mL bottle of acid reagent required for determination of total sulfur dioxide in wine using the HI84100 Sulfur Dioxide Mini Titrator for Wine Analysis.*

This acid reagent is used to lower the pH value of the sample prior to performing a titration. With 5 mL of reagent required per test, there is enough acid 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
  • Air tight bottle with tamper-proof seal

Description

The HI84100-52 acid reagent is necessary to lower the pH of the wine sample before a titration can be performed for total sulfur dioxide. The adjustment of the wine sample with 5 mL of the HI84100-52 acid reagent ensures the sample is at the correct pH. 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 + 3H2O

The iodine produced reacts with sulfur dioxide in the wine according to the redox reaction below:

H2SO3 + I2 → H2SO4+ 2HI

Replacement reagents required to operate the HI84100 include:

Titrant solution HI84100-50
Alkaline reagent for total SO2 HI84100-51
Acid reagent for total SO2 HI84100-52
