WebMay 4, 2024 · Updated on May 04, 2024. A buffer is a solution containing either a weak acid and its salt or a weak base and its salt, which is resistant to changes in pH. In other words, a buffer is an aqueous solution of either a weak acid and its conjugate base or a weak base and its conjugate acid. A buffer may also be called a pH buffer, hydrogen ion ... WebSep 27, 2016 · δ + Δ = log([A −] + α [HA] − α) One then notes that bases attempt to increase the pH of a solution so Δ = 1, and also let us denote βb as the buffer base capacity. Also, note that α = βb. We are interested in …
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. WebHowever, with a buffer present, since there is a weak acid, HA, present to neutralize the added hydroxide anions, the buffer solution resists a change to the pH. So let's …
