Buffer

Buffer. A solution that can resist a change in pH when an acid or a base is added to it. Buffer capacity. The amount of acid or base that a buffer can withstand before the pH changes. PH – depends on the Ka and the concentration of acid/base pairs. Henderson Hasselbalch equation.

  1. Buffer A solution that can resist a change in pH when an acid or a base is added to it.

  2. Buffer capacity The amount of acid or base that a buffer can withstand before the pH changes.

  3. PH – depends on the Ka and the concentration of acid/base pairs

  4. Henderson Hasselbalch equation PH = pKa + log [base] [acid]

  5. Normality number of equivalents in 1 liter 1M HCl H+ + Cl- 1 normal solution 1M H2SO4H+ + HSO4-2 normal solution HSO4-H+ + SO42-
