Suppose you wanted to analyze the amount of metal in the alloy. For example, you might want to determine the nickel (Ni2+) content in alloy material. (a) Using gravimetric analysis, propose precipitating method to analyze nickel (Ni2+) in alloy and write 8 steps required during the precipitation. Also, suggest an appropriate solvent and its ratio dissolve the mixture. Here we recommended using dimethylglyoxime (H2DMG) as an organic precipitating agent.

(b) Suppose the nickel had been precipitated from the alloy (2.0980g) using dimethylglyoxime (H2DMG) as an organic precipitating agent and giving a precipitate of complex nickel dimethylglyoxime (Ni(HDGMG)2) weighing 0.2370g. Calculate the percentage weight of nickel (Ni2+) in the alloy sample.
