Ni content of the steel can be determined by the precipitation gravimetric analysis. For this purpose, 1.000 g of a steel sample is taken and interacted with the concentrated HCI solution. After neutralizing the resulting mixture in the presence of citrate ions, 1% dimethyl glyoxime (DMG) solution is slowly added to precipitate Ni(II) ions as Ni(DMG)2. What is the percentage of nickel in this steel sample, if 0.2269 g of Ni(DMG), (288.93 g/mol) is obtained?

1. Aluminum is determined gravimetrically by precipitating Al(OH)3 and isolating Al½O3. A sample that contains approximately 0.1 g of Al is dissolved in 200 mL of H2O, and 5 g of NH4C1 and a few drops of methyl red indicator are added (methyl red is red at pH levels below 4 and yellow at pH levels above 6. The solution is heated to boiling and 1:1 NH3 is added dropwise until the indicator turns yellow, precipitating Al(OH)3. The precipitate is held at the solution's boiling point for several minutes before filtering and rinsing with a hot solution of 2% w/v NHẠNO3. The precipitate is then ignited at 1000–1100 °C, forming Al>O3. a) Cite at least two ways in which this procedure encourages the formation of larger particles of precipitate. b) The ignition step is carried out carefully to ensure the quantitative conversion of Al(OH)3 to Al203.
