Write down the reactions that take place when the weak strong acids—HF, HNO2, HCN, CH3COOH, and H3PO4—are dissolved in water. For each reaction, label the acid, base, conjugate acid, and conjugate base.

Solutions

Expert Solution

HF(aq) + H2O(l) <---> H3O+(aq) + F-(aq)

HNO2(aq) + H2O(l) <---> H3O+(aq) +NO2-(aq)

HCN(aq) + H2O(l) <---> H3O+(aq) + CN-(aq)

CH3COOH(aq) + H2O(l) <---> H3O+(aq) + CH3COO-(aq)

The triprotic acid:

H3PO4(aq) + H2O(l) <--> H3O+(aq) + H2PO4-(aq)

H2PO4-(aq) + H2O(l) <--> H3O+(aq) + HPO4-2(aq)

HPO4-2(aq) + H2O(l) <--> H3O+(aq) + PO4-3(aq)

Overall

H3PO4(aq) + H2O(l) <--> 3H3O+(aq) + PO4-3(aq)

Unlike strong acids and bases that ionize completely in solution, weak acids or bases partially ionize. The tendency to ionize (i.e., the ionic strength) of a weak acid or base can be quantified in several ways including Ka or Kb, pKa or pKb, and percent ionization. Part A Pyridine is a weak base that is used in the manufacture of pesticides and plastic resins. It is also a component of cigarette smoke. Pyridine ionizes in water as follows: C5H5N+H2O⇌C5H5NH++OH− The...
