1. (a) (i) molar shoulder maximum at 312 nm containing the two cell) of 0.726 and 0.544 at concentrations of compound A (3 marks) Compound A and B absorb in the ultraviolent region. Compound A exhibits an absorption maxima at 267 nm (a=157) and a trailing at 312 nm (a=12.6). Compound B has an absorption (a=186) and does not absorb at 267 nm. A solution compounds exhibits absorbance (using a 1 cm - 267 and 312 nm respectively. Calculate the and B in mg/l. (ii) A mine (weak base) from salts with picric acid (trinitrophenol), and all amine picrates exhibit an absorption maximum at 359 nm with a absorptivity of 1.25 x 104 .0.2 g sample of aniline, C6H5NH₂ is dissolved reacted with picric acid in a 250 volume. A 10.0 ml a liquor of this is read at 359 nm in a 1 cm cell. If the 1 percent purity of the aniline. (3 marks) in 500 ml of water.
