#1
正面 (问题)

Buffer definition:

背面 (解答)

A solution that minimises the pH change when small amounts of acid or alkali are added

#2
正面 (问题)

Components of a buffer solution:

背面 (解答)

Weak acid and its conjugate acid-base pairing, in order to remove any added OH- or H+ (equilibrium)

#3
正面 (问题)

Action on a buffer solution when acid is added:

背面 (解答)

• H+ increases • Excess H+ reacts with A- (conjugate base pair) • Equilibrium shifts back to the left, so most of the added H+ ions get used

#4
正面 (问题)

Action on a buffer solution when alkali is added:q

背面 (解答)

• OH- increases • Small volume of H+ reacts to form water (H2O) • Equilibrium shifts to the right to restore the volume of H+ ions
