A K2SO4•Al2(SO4)3•24H2O preparation is tested for its purity by converting first to Al(OH)3 then finally to Al2O3. If you start with a 1.2391 g K2SO4•Al2(SO4)3•24H2O and obtained 0.1357 g Al2O3 (A). What can you say about the obtained purity value? Is it acceptable? (B). Which is a better choice of precipitate for the quantitative analysis of K2SO4•Al2(SO4)3•24H2O, Al(OH)3 or Al2O3? Explain
