Hanna, HI3844-100, Hydrogen Peroxide Chemical Test Kit Replacement Reagents (100 tests)

The HI3844-100 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate hydrogen peroxide measurements with the chemical test kit. These reagents follow an iodometric titration method to determine hydrogen peroxide concentration.
For determination of hydrogen peroxide, a slow reaction with iodide in acidic solution occurs with the hydrogen peroxide present in the sample. 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. The number of drops of titrant used to reach the visual endpoint will determine the hydrogen peroxide as mg/L H 2 O2. These reagents are designed to be used with samples that have an expected hydrogen peroxide range of 0.00 to 2.00 mg/L and 0.0 to 10.0 mg/L H 2 O2.
