Abstract Pyrorle-2-aldehyde and 1‚3-diaminopropane react under reflux to form a transition metal ion of Nickel(II)‚ that further more react with nickel acetate to form red crystals through condensation‚ the colour being constituded by the congugated bonds. These series of reactions synthesize the Schiff Base ligand and Nickel(II) complex of the Schiff base ligand. 0.36g of the Schiff base ligand is yielded and 0.1g of the nickel complex is yielded from the 0.36g Schiff base ligand and 0.5g nickel

INTRODUCTION 1.1. Nickel Nickel is a chemical element with atomic number 28. It is denoted by the symbol ‘Ni’ and is one of the main constituent of meteorites. It was discovered in 1751‚ by Axel Fredrik in Sweden. It belongs to the transition metal group and is known for its hardness and ductility. Significant chemical reactivity is exhibited by pure Nickel. Nickel in its pure or low-alloy form is used in several fields as it is highly resistant to various reducing chemicals. Nickel when annealed

indicate the end point of a titration) titrations as it forms stable complexes with most metal ions. EDTA is a tetracorboxylic acid and in alkaline conditions‚ it exists as Y⁴⁻ ions‚ which form 1:1 complexes with metal ions like nickel(II) ions: Y⁴⁻ + Ni²⁺ NiY²⁻ A metal ion indicator (an organic dye which changes colour when it binds with metal ions) shows the end of an EDTA complexometric titration. However‚ for a metal ion indicator to be suitable in n EDTA titration‚ it must not bind as strongly
