The magnitude of the equilibrium constant for an ionization reaction can be used to determine the relative strengths of acids and bases. The implications of the above chemistry is that in addition to the cited Reaction (1) above (which is a sink for the removal of the hydroxyl radical, that otherwise could be involved in an ozone depletion cycle), the UV photo-induced decomposition of also gaseous H2SO3 likely leads to more problematic radicals cited in the acid rain formation and even ozone depletion. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Sulfuric acid is a colourless oily liquid. What am I doing wrong here in the PlotLegends specification? As we noted earlier, because water is the solvent, it has an activity equal to 1, so the \([H_2O]\) term in Equation \(\ref{16.5.2}\) is actually the \(\textit{a}_{H_2O}\), which is equal to 1.
