6. The amount of nickel (FM 58.693) in steel can be determined with the precipitating agent dimethylglyoxime (DMG, C4H8O2N2, FM 116.12). The steel is dissolved in acid, the solution is neutralized, then the DMG is added to precipitate the nickel as the complex bis(dimethylglyoximate)nickel(II) (Ni(C4H7O2N2)2, FM 288.91) according to this reaction: Ni2+(aq) + 2C4H8O2N2(aq) → Ni(C4H7O2N2)2(s) + 2H+(aq) DMG has limited solubility in water and may precipitate with the complex, so it is important to avoid adding an excess of the precipitating agent. a) If the mass percent of nickel in a certain steel sample is believed to be approximately 2.0%, what volume of 1.0 wt% dimethylglyoxime solution with a density of 0.83 g/mL should be used with a 1.5-g steel sample to give a 25% excess of DMG? b) If a 1.458 9-g sample of steel produced 0.150 6 g of precipitate, what was the mass percent of nickel in the sample?
