Buffering system equation
WebBuffer solution two also consists of acidic acid and the acetate anion. However, in this case, both concentrations are 0.0250 molar. So buffer solution one has a higher concentration of both acidic acid and the acetate anion. Let's calculate the initial pH of both buffer solutions using the Henderson-Hasselbalch equation. WebJun 9, 2024 · The original buffer factor β is based on pH (Equations 13 and 19), but Egleston et al. and Hofmann, Middelburg, et al ... (Revelle sensitivity factor) as a function of pH for average seawater. The carbonic acid system dominates the buffering capacity of seawater and these sensitivities thus show extrema related to the pK 1 (≈5.9) and pK 2 ...
