In fact, the Ka values for all weak acids are all very small so we employ the same logic as that of pH and use the negative log which means we use the letter p. Thus, the pKa for acetic acid is 4.73. Also, like the ... WebMay 4, 2024 · Updated on May 04, 2024. A buffer is a solution containing either a weak acid and its salt or a weak base and its salt, which is resistant to changes in pH. In other words, a buffer is an aqueous solution of either a weak acid and its conjugate base or a weak base and its conjugate acid. A buffer may also be called a pH buffer, hydrogen ion ...
