GRAVIMETRIC ANALYSIS The addition of dimethylglyoxime, H2C4H602N2, to a solution containing nickel(Il) ion gives rise to a precipitate: Nickel dimethylglyoxime is a bulky precipitate that is inconvenient to manipulate in amounts greater than 135 mg. The amount of nickel in a type of permanent-magnet alloy ranges between 22% and 38%. Calculate the sample size that should not be exceeded when analyzing these alloys for a nickel.
JJ Techie calcined some ceramic powders at 1600℃ for 12 hrs, when removed from thefurnace, JJ was upset to find a big hard lump., After grinding up to the lump, someone told JJ to add a sintering aid and deflocculant to the ceramic before trying to press it into cylinders 10 inch by 0.25 inch in diameter. How could JJ do this well? JJ needs this size ceramic rod for experiments.

(a) 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.
