WebA buffer is a solution that resists changes in pH, and it generally consists of a weak acid and its conjugate base. There are two ways of making a buffer solution. The first way is to start with an aqueous solution of a weak acid and then add a soluble salt that contains the conjugate base. The second way to make a buffer solution is to start ... WebSo the negative log of 5.6 times 10 to the negative 10. Is going to give us a pKa value of 9.25 when we round. So pKa is equal to 9.25. So we're gonna plug that into our Henderson-Hasselbalch equation right here. So the pH of our buffer solution is equal to 9.25 plus the log of the concentration of A minus, our base.
