• The standard working pH range is 2.0 to 12.0. • 1 mg sample powder or 50µL of a 10 mM DMSO stock aolution is required 5 Table 5. A comparison of the two methods used to determine pKa. As drug-like molecules are often poorly water soluble, a water-miscible co-solvent can...
Ka=(new H30+)(x+concentration Na0H)/(initial-x-conc. Na0H) after finding the new H30+, find the pH. Subtract this from 6.03 and from here you can deduce the Ka2. HH equation: pH = pKa2 + log([Ma(2-)]/[HMa-]) rearranging: pKa2 = pH + log([HMa-]/[Ma(2-)]) using calc...

Approximately 7% of all reported tuberculosis (TB) cases each year are recurrent, occurring among people who have had TB in the recent or distant past. TB recurrence is particularly common in India, which has the largest TB burden worldwide. Although pat
