Unit 2 PPA 1 Complexometric Determination of Nickel using EDTA Introduction: The Aim of the experiment is to determine the percentage of nickel salt using a complexometric technique. Ethylenediaminetetraacetic acid (EDTA) is a hexadentate ligand which forms stable complexes with most metal ions‚ thus is widely used to determine metals in complexometric titrations. EDTA can be represented as H4Y and in alkaline conditions‚ it exists as Y+ ions: The Y4- ions form 1:1 complexes with metal ions
