1. Thermodynamics and acid solutions a) The following reaction occurs when HCl is bubbled into water at 25°C and latm pressure: HCl(g) -> H+(aq) + Cl (aq) Calculate AS rxn for this reaction. b) Sketch two possible structures of the hydronium ion in water. Circle the hydronium ion in each case. Also sketch the local structures of water surrounding the hydronium and chloride ions in aqueous solution. Include the important water molecules in both sets of sketches. c) Draw a...
