Houston, texas became known the city of syrup after the conviction of 6 pharmacists for improper, illegal distribution of 2500 gallons of codeine cough syrup for the production of purple drank . Acids: strong acids: low ph = 3, low pka = 3, weak acids: high ph = 13, high pka = 13. Bases: strong bases: high ph = 13, high pka =13, weak bases: low ph = 3, low pka = 3. When ph = pka, then the drug is half ionized and half nonionized.
