WebWe can relate pKa values to the pH of a solution by the Henderson–Hasselbalch equation which is: pH = pKa + log ( [A-]/ [HA]), where A- is the conjugate base and HA is the acid. The Henderson–Hasselbalch determines the pH of buffers where a buffer is essentially a solution of a weak acid and a consequential amount of its conjugate base. WebThe pKa measures how tightly a proton is held by a Bronsted acid. A pKa may be a small, negative number, such as -3 or -5. It may be a larger, positive number, such as 30 or 50. The lower the pKa of a Bronsted acid, the more easily it gives up its proton.
