Formula henderson hasselbalch
WebDec 20, 2024 · Using the Henderson Hasselbalch equation, you can estimate the pH of a buffer solution given the concentrations of the acid and its conjugate base, or the base … A simple buffer solution consists of a solution of an acid and a salt of the conjugate base of the acid. For example, the acid may be acetic acid and the salt may be sodium acetate. The Henderson–Hasselbalch equation relates the pH of a solution containing a mixture of the two components to the acid dissociation constant, Ka of the acid, and the concentrations of the species in solution.

WebJan 30, 2024 · We can simplify the above equation: (7) p K a = p H − log [ A −] If we add log [ A −] to both sides, we get the Henderson-Hasselbalch approximation: (8) p H = p K a + log [ A −] This approximation is only valid when: The conjugate base / acid falls between the values of 0.1 and 10. The molarity of the buffers exceeds the value of the K ...
WebSo a ratio of the moles is the same thing as a ratio of the concentrations in the Henderson-Hasselbalch equation. And we can get our moles directly from our ICF table. So the moles of the acetate anion are equal to 0.270, and the moles of a acidic acid is equal to 0.230. And when we solve for the pH, we find the pH of the solution is equal to 4.81.
