Product Description

The HI 3844 test kit can quickly and easy determine concentration in water up to
10 ppm 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. The kit is portable and can be used in the field as well as in the laboratory.

Hydrogen peroxide is determined by a titrimetric method. It 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–
