    SOLVED:Amines (weak base) form salts with picric acid (trinitrophenol), and all amine picrates exhibit an absorption maximum at 359 nm with a molar absorptivity of 1.25 ×10^4 . A 0.200-g sample of aniline, C6 H5 N H2, is dissolved in 500  mL water. A 25.0 -mL aliquot is reacted with picric acid in a 250 -mL volumetric flask and diluted to volume. A 10.0 -mL aliquot of this is diluted to 100  mL and the absorbance read at 359: nm in a 1-cm cell. If the absorbance is 0.425 what is the percent puri
