9. To determine the phenol content of the analyzed water, acid and excess potassium bromide were added to a 100 ml water sample and coulometric titration of phenol was performed with electrogenerated bromine at a direct current of 10 mA. To complete the reaction
C6H5OH 3Br2 = C6H5(OH)Br3(s) 3HBr
It took 5 min 34 sec.
Calculate the concentration (μg/l) of phenol in the analyzed water (M.w. phenol 94.117 g/mol.) How is the titrant obtained in this titration? What generator electrode is used? Write the equation of the corresponding reaction.
