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.
To determine the Kgp of barium oxalate at 12°C, a 100.0 mL saturated solution was prepared by adding the solid in distilled water maintained at 12°C until it no longer dissolves. The solution was filtered and from this, a 10.0 mL aliquot of the filtrate was drawn. It was found out that 10.70 mL of 5.60 x 104 M HCI was used to reach the endpoint. Given that two moles of HCl react for every mole of dissolved oxalate during the titration, determine the amount of dissolved oxalate in the titration flask (in mol/L). Do not include the unit in your answer below. For those who will be using scientific notation, please follow the format below: Example: 0.00487 -> 4.87E-3 58000 -> 5.8E+4
