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.
