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 apparatus was collected: 50cmᶟ burette ●Glass stirring rod 20cmᶟ pipette ●Hydrated nickel(II) sulphate (NiSO₄.6H₂O) 100cmᶟ standard flask ●Standardised 0.10moll⁻¹ EDTA solution 250cmᶟ conical flask ●1 moll⁻¹ ammonium
