Hydrogen Peroxide Chemical Test Kit - HI3844

$163.00

The HI3844 is a chemical test kit that measures hydrogen peroxide by iodometric titration. The HI3844 is supplied complete with all of the reagents and equipment necessary to perform approximately 100 tests.

  • Pre-made reagents for ease of use
  • All reagents marked with expiration date and lot number for traceability
  • Manual titration performed with starch indicator
The HI3844 is a titration-based chemical test kit that determines the hydrogen peroxide concentration in two ranges: 0.00 to 2.00 mg/L and 0.0 to 10.0 mg/L. The HI3844 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents for perform approximately 100 tests.

Features at-a-glance

  • Complete setup
    • All required materials are included with the test kit, such as the sample beaker, indicator and reagent bottles, spoon, and plastic pipettes.
  • High resolution
    • Readings from 0.00 to 2.00 mg/L are determined to 0.25 mg/L resolution.
    • Readings from 0.0 to 10.0 mg/L are determined to 1.0 mg/L resolution.
  • Replacement reagents available
    • There is no need to buy a new kit when reagents are exhausted. The HI3844-100 can be ordered to replace the reagents supplied with the kit.

 

Significance of Use

Hydrogen peroxide (H2O2) is widely used as a disinfectant and as a bleach for textiles, wood pulp, and hair, just to name a few. It is also used as a substitute for chlorine in water and sewage treatment. Most common commercial forms are aqueous solutions containing about 6, 12 and 30% hydrogen peroxide and are referred to as “20-volume, ” “40-volume, ” and “100-volume” respectively, referring to the value of oxygen liberated when the solution is boiled. The Hanna test kit can quickly and easily determine concentration in water up to 10 mg/L of hydrogen peroxide. This is due to the fact that it is not affected by stabilizers, which are sometimes added to commercial hydrogen peroxide solutions.

In the HI3844 test kit, hydrogen peroxide reacts slowly with iodide in acid solution (Step 1); thus a 15 minute interval is required to allow the reaction to occur completely. The amount of iodine generated is equivalent to the hydrogen peroxide in the sample. The liberated iodine is then titrated with standard sodium thiosulfate solution that reduces the iodine back to iodide ions (Step 2).

Step 1: H2O2 + 2H+ + 2I → I2 + 2H2O

Step 2: I2 + 2(S2O3)2- → 2I + (S4O6)2-
