Acid Reagent for Free Sulfur Dioxide - HI84100-53
SKU: HI84100-53
This product is considered hazardous to ship and is subject to extra handling fees.
This product is freeze sensitive and is subject to extra handling fees from November 15th to April 15th.The HI84100-53 is a 500 mL bottle of acid reagent required for determination of free 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
The HI84100-53 acid reagent is necessary to lower the pH of the wine sample before a titration can be performed for free sulfur dioxide. The adjustment of the wine sample with 5 mL of the HI84100-53 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 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
