The Gravimetric Estimation of Nickel: The nickel is precipitated as nickel dimethyl glyoxime by adding alcoholic solution of dimethyl glyoxime C 4 H 6 (NOH) 2 and then adding a slight excess of aqueous ammonia solution. When the pH is buffered in the range of 5 to 9, the formation of the red chelate …Experiment: Gravimetric Determination of Nickel The purpose of this experiment is to determine the % nickel (by weight) in an unknown nickel-containing ore by means of gravimetric methods. INTRODUCTION The separation of nickel from other ions in a sample is a good example of specificity in quantitative analysis.Experiment: Gravimetric Determination of Nickel

Gravimetric Determination of Nickel using Dimethylglyoxime. Add the fused mass to the filtrate from the acid treatment. Evaporate to dryness to dehydrate the silica, add 50 cc’s of dilute HC1, and Boil the filter. Was with hot water until total volume is 100 cc’s. Pass hydrogen sulphide into the acid treatment or fusion as the case may be.The Gravimetric Estimation of Nickel: The nickel is precipitated as nickel dimethyl glyoxime by adding alcoholic solution of dimethyl glyoxime C 4 H 6 (NOH) 2 and then adding a slight excess of aqueous ammonia solution.
