I conducted the synthesis of an Alum experiment in my lab last week and I'm working on my report. I'm almost done expect I don't know how one could increase the yield of the product (alum crystal)? And also what is the point of adding sulfuric acid? Can anyone help me out?

    There is more than one kind of alum and I don't know the details of the experiment you conducted. Alums, by definition, are composed of the sulfates of a monovalent and a trivalent metal and usually containing a specific number of moles of hydration. A possible reason for adding the H2SO4 could be to form th sulfate part of the molecule. Here is a site that talks more about alums.

    In my experiment we produced KAl(SO4)2.12H2O
