FOSSIL FUELS: pH EFFECTS Notes to the teacher : Students will prepare oxides of metals (Mg and Fe) by burning in air. Oxides of nonmetals (C, S, and N) are made by preparing carbonic acid (H 2 CO 3 ), nitrous acid (HNO 2 ), and sulfurous (H 2 SO 3 ) acid in double replacement reactions and collecting these gases above the reaction solution. These double replacement reactions are performed in Beral pipets, and the gases are trapped in the pipets, ready to be collected for pH testing. The part of this lab that deals with pH testing was based on a laboratory exercise called Acid Rain (Holmquist, DD and Volz, DL. Chemistry with Computers . Portland, oregon, Vernier Software, pp 22.1 - 22.2T. Consult standard laboratory manuals for instructions to prepare1 M HCl. A class of 32 students should need about 250 cm 3 of 1 M HCl. Boil the distilled water and then stopper it to prevent CO 2 from dissolving in it. This lab can also be used in a unit on acids and bases or on a unit about periodic properties.
