TīmeklisLooking at the Henderson-Hasselbalch equation, if the concentration of HA is 10 times the concentration of A-, the ratio is equal to one over 10, and the log of one over 10 is equal to negative one. Therefore, the pH of the buffer solution is equal to the pKa value of the weak acid minus one. Tīmeklis2024. gada 27. jūl. · The buffer capacity is optimal when the ratio is 1:1; that is when pH = pKa. 2. Total Buffer Concentration: Buffer capacity depends upon the total buffer concentration.
