1. A strong acid would have a pKa: a. greater than 12. b. less than 2. 2. The major number of drugs available today would be classified as: a. proton donors b. proton acceptors A pharmacist must understand the definition of acids/bases. The BRÖNSTED-LOWREY model defines an acid as a proton (H') donor and a base as a proton (H*) acceptor. Recognition of a non-ionized drug as an acid or a base is necessary to calculate its percent ionization. When...

Predicting pH
Imagine you have a 0.125 M aqueous solution of aspirin, an acid drug with pKa = 3.5, in equilibrium. a) Estimate the pH of the solution Hint: Determine if it is an acid or base solution, weak or strong If weak acid/base, first try (H+) = /K,C, or [OH-] = K,C, b) Predict what would happen to the pH when you add more H2 Hint: First figure out what happens to the concentrations HA(aq) + H2O(0) A (aq)...
