17.2 Buffered Solutions
Solution of a weak acid and its conjugate base in approximately equal concentrations
Addition of a strong acid or base shifts the pH only slightly
HF(aq) + H2O(l) ? H3O+(aq) + F-(aq)
Add HCl, equilibrium shifts to left to consume some of added H3O+
Kotz CD: 18m08an2 HCl + H2O
Kotz CD: 18m08an1 HCl + buffer
