“Excuse me, but I am confused and in a dilemma. On Raci.org.au they say that this is potassium alum KA1(SO4)2⋅12H2O. However on this website you claim that this is ammonium aluminum sulfate Al(SO₄)₂·12H₂O. Which by the way is incorrect because the metal needs to come first, therefore it should be called aluminum ammonia sulfate. I am a classy freshman in high school who needs reliable information. I was given false hope and a false heart attack because of the name of alum. My research project/life's work was almost ruined. Please correct your shortcomings to prevent future problems/ incidents. ”
