1 Experiment 17 Classification of Chemical Substances Sample Raw Data NOTE: All boxes left empty represent experiments not done (because they were deemed not needed to make a reasonable final conclusion) What you need to do is make a conclusion about which of the four classes of solids each substance is. You must give reasoning in each case, although you need not write a book (the lab manual s report form, however, give you literally no room! So write your reasoning on the back of this form or on a separate sheet of paper. Table substance No. Approx.
