- Buffers should have a pKa between 6.0 and 8.0 because the optimal pH for most biological reactions rests in this range.
- Buffers should have high water solubility and minimum solubility in organic solvents so it remains in the aqueous medium of the biological system.
What is the best buffering system?
1. A pKa between 6 and 8. Most biochemical experiments have an optimal pH in the range of 6–8. The optimal buffering range for a buffer is the dissociation constant for the weak acid component of the buffer (pKa) plus or minus pH unit.
What types of solutions serve as good buffers?
Types of Buffer Solutions
Buffers are broadly divided into two types – acidic and alkaline buffer solutions. Acidic buffers are solutions that have a pH below 7 and contain a weak acid and one of its salts. For example, a mixture of acetic acid and sodium acetate acts as a buffer solution with a pH of about 4.75.
