One student can add the magnesium ribbon to the acid and stopper the flask, while the other starts the stopclock. In the third flask there is one quarter of the stoichiometric quantity of Mg so the balloon is noticeably smaller than the other two since the Mg is used up before all of the HCl is converted to hydrogen gas and the indicator stays red, showing that there is still acid present. Randy Sullivan, University of Oregon There is some acceleration of the reaction rate due to the rise in temperature. For the reaction $\ce{2H3O+ + Mg -> H2 + Mg^{-2}}$; the actual rate law is Turn on the camera and focus it.
