A Stoichiometric Study on The Reaction Between Ferric Ion and p-Chloro – N- Phenyl –p-Chlorobenzo hydroxamic acid

A stoichiometric study on the reaction between ferric ion (Fe (III)) as metal and p-Chloro – N- Phenyl –p-Chlorobenzohydroxamic acid as ligand ((abbreviated in this paper as PCNPPCBHA)) was attempted. The ligand PCNPPCBHA was synthesized^(1),(2) and identified.^(3),(4) The pH at maximum extraction of the ligand PCNPPCBHA to the metal iron (III) was determined spectrophotometrically and the ratio of the ligand: metal i.e. PCNPPCBHA: Fe⁺³ was determined by the use of the continuous variation method and confirmed by the slope ratio method.
