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 with metal ions as EDTA does. Murexide is therefore suitable. AIM The aim of this experiment is to determine the percentage of nickel in a nickel(II) salt using EDTA. METHOD The following

The element of Nickel is number 28 which means it has 28 electrons and 28 protons (this is the atomic number). The atomic mass of Nickel is 58.71 g.mol^-1 which means that there are 30.69334 neutrons since you subtract the number of protons from the atomic mass to get the number of neutrons. The electronegativity of Nickel is 1.8 on the Pauling scale; this is the tendency of Nickel to attract a bonding pair of electrons. The density of Nickel is 8.9 g.com^-3 at 20°C and the melting point is 1454
