SWIM's been on a shopping spree gearing up, and got back with some nitric, sulfuric and Hcl.
Now SWIM has read about different conc. of acids according to different methods. Problem is, SWIM doesn't know the conc. of his/her acids. So, how can he/she tell? Boiling them and getting the boiling point?? Or somehow measuring that Baume thing? (If that is easily measurable for someone like SWIM)
