1. 10 points. (a) Make a case for assuming that the hydronium ion is in a more complex form than H,O in solution: for example, H,O2. (Hint: Can the H" ion attach to more than one water molecule ?) (b) Make a case for assuming that the hydroxide ion is in a more complex form than OH in solution. 2. 10 points. Identify the acid-base conjugate pairs in the following four equilibrium reactions, and identify the acid and base species in each pair: (c) HCO, (aq) + Ho (aq) HCO, (aq) HO)
