Abstract:
This study was conducted to determine the content of Nickel(II) Chloride In NiCl2.6H2O by gravimetric and volumetric methode. In gravimetric method the content of Nickel(II) Chloride was determined using repetly of heating and weighing sample with several kinds of laboratory equipment such as, watch glass, beaker, steam bath, oven desicator,etc.in gravimetric we using Chloride Acid 6M, H2DMG 1% solution, and NH4OH dilution for the materials. In gravimetric method the content of Nickel(II) Chloride is 21,95%. while in volumetric method the content of Nickel(II) Chloride was determined using titration with Hg(NO3)2 solution with diphenyl carbazone indicator in sample the tools are important in this method is Burrete and titration flask. the first step is standarization of Hg(NO3)2 with NaCl to determine concentration of titrate that is 0,0205 M. from volumetric method we got the content of Nickel(II) Chloride is 82,64%. So in this studied we can conclude that volumetric method more accurate than gravimetric method.
