Product description
To determine 8-hydroxyquinoline, the test solution was coulometrically titrated with bromine electrogenerated from KBr in the presence of H2SO4 at a constant current of 6.0 mA. The end of the reaction was determined biamperometrically.
Find the amount of 8-hydroxyquinoline (mg) if the electrolysis time was τ=100 s, and 4 meq of bromine is required to oxidize 1 mole of oxyquinoline:
