Ph of an acidic buffer mixture is
WebChapter 16: Buffers and Titrations Ch16.1 Buffer Solutions. A mixture of a weak acid and its conjugate base (or a mixture of a weak base and its conjugate acid) is called a buffer solution, or a buffer.Buffer solutions resist a change in pH when small amounts of a strong acid or a strong base are added (Figure 1). WebpH = p K a + log [ A −] [ HA] where p Ka is the negative of the logarithm of the ionization constant of the weak acid (p Ka = −log Ka ). This equation relates the pH, the ionization …
