Ph of antibiotics
WebWhen the pH is lower than the pKa, the un-ionized form of a weak acid predominates, but the ionized form of a weak base predominates. Thus, in plasma (pH 7.4), the ratio of un-ionized to ionized forms for a weak acid (eg, with a pKa of 4.4) is 1:1000; in gastric fluid (pH 1.4), the ratio is reversed (1000:1).
