Product Description

34. We carried out coulometric titration of the arsenite ion AsO32- in a weakly alkaline test solution with electrogenerated iodine I2 at a constant current w = 2.5 * 10-3 mA in the presence of an indicator - starch. During titration the reaction occurs:
AsO5 I2 H2)=AsO4 2I 2H. The solution turned blue 6 min 26 s after the start of titration. Calculate the mass of arsenic (III) in the analyzed solution.
