You have a Magnox sample that weighs 1 g. Knowing that it is an alloy, all the other interferents are removed prior precipitating the Al and Mg. The precipitant of choice for this to happen is 8-hydroxyquinoline. After the ignition process, you obtained a precipitate with aluminium oxide and magnesium oxide. The weight of all precipitates is 7.98 g. The final weight after ignition is 0.98 g. Compute for the % composition of aluminium and magnesium your Magnox sample.
