Practical B Sc- III Experiment:- Prepare Nickel-DMG complex from given resources.    Do watch this video, link given below for experment. https://www.youtube.com/watch?v=peMyqdJ57dA Requirements:- Chemical Required-NiSO4 or NiCl2.6H2O, Di-methyleglyoxime, Conc. NH3 , HCl.   Apparatus-    Beaker (100ml, 50ml, 20ml), Thermometer, heating plate or water bath, conical funel, stand, distilled water, filter paper. Theory:   Gravimetric analysis is one of the most accurate analytical methods available. It is concerned with the determination of a substance by the process of weighing. The element or radical to be determined is converted into a stable compound of definite composition and the mass of the compound is determined accurately. From this, the mass of element or radical is calculated. Chemical Reaction Objectives:   To precipitate nickel from the solution by adding dimethyl glyoxime. Filtration of precipitate using sintered glass crucible. Mass of nickel calculated from the mass of prec
