Voice ISensitivt 1. H2S can be analyzed by coulometric titration, in which I2 is generated as part of the reaction: 21 + 2c The generated 2 reacts with H2S L +H2S → So + 2H + 2I If 80.0 mL sample, containing excess KI, required 715 second at 125.8 mA for electrolysis to be complete, a. calculate the molar concentration of H2S (34,1 g/mole) in the 80.0 mL sample. b. Assuming the density of the sample 100 g/mL, calculate the concentration of H2S (34.1 g/mole) expressed in ppm. If the 80.00 mL sample was originally prepared from 10.00 mL sample, what is the molar concentration of H2S in the original 10.00 mL sample? Voice ISensitivt 1.
