Ampicillin trihydrate \((12.5-575 \mu \mathrm{g})\) and amoxycillin trihydrate \((10-400 \mu \mathrm{g})\), in \(25-\mathrm{ml}\) total volume, are determined spectrophotometrically using picric and picramic acids as \(\pi\)-acceptors at \(\mathrm{pH} 9\). The method is relatively accurate (with a r
