1 Ratio of the salt to the acid or base. 2  The buffer capacity is optimal when the ratio is 1:1; that is, when pH = pKa. 3  Total buffer concentration. 4  For example, it will take more acid or base to deplete a 0.5 M buffer than a 0.05 M buffer.
A buffer with a pH=10.00 is to be prepared from the (CH 3) 3 N/ (CH 3) 3 NHCl system with K B =6.3x10 -5. What concentration ratio of base to salt should be used? Calculation of Buffer pH After Addition of Strong Acid or Base Q A buffer solution is 0.10 M HC 2 H 3 O 2 (K A = 1.8x10 -5) and 0.20 M NaC 2 H 3 O 2.hem 116116-buffers4 Sample Questions 1. Calculate the pH of a buffer solution that is 0.45 M in NH 4 Cl and 0.15 M in NH 3. (8.77) 2. Calculate the pH of a buffer solution that is 0.25 M in HNO 2 (K A =7.1x10 -4) and 0.15 M in NaNO 2 .3.
