WebThe conjugate base of a strong acid would be an exceedingly weak base and so it would be severely limited in neutralizing additional acid. Essentially the addition of more acid would lower the pH even more so. The purpose of a buffer is to resist these drastic changes in pH so a strong acid buffer wouldn't really be achieving that. WebThe term "buffer capacity" (β) quantifies the change in pH of the solution caused by the addition of a strong acid or base. It is calculated in relation to 1 dm3 of a buffer solution. …

WebBecause at 25 degrees Celsius, the pKa value for acetic acid is equal to 4.74. Therefore, this buffer would only be effective at a range of plus or minus one from 4.74, so about … WebSo let's go ahead and look at all the possible scenarios for these three things. We're going to start with the simplest possible scenario, which is that pH is equal to pK_a. When pH is equal to pK_a, we're raising 10 to the zeroth power. So anything to the zeroth power is equal to one. Which tells us that this ratio is equal to one. rejection interview response
