The Henderson-Hasselbalch approximation is derived from this acid ionization constant. Equation 8.8.6 8.8.6 is formulated in terms of equilibrium concentrations in solution. Since HA H A is a weak acid and weakly dissociates and we can introduce two approximations. [HA] ≈ [HA]i (8.8.7) (8.8.7) [ H A] ≈ [ H A] i. As an example of how to use the Henderson-Hasselbalch equation, let's find out what species are present in a 0.0010 M solution of acetic acid at pH = 7.3. According to Table 20-3, the pK a of acetic acid is 4.76. From the Henderson-Hasselbalch equation, we have 緩衝液のpHの求め方（ ヘンダーソン-ハッセルバルヒの式）. H+とA-に解離する弱酸HAは以下の平衡式で表されます。. HA ⇌ H+ + A-. この式が成り立つとき、. 解離定数とpHの関係は以下の式で表されます。. pH = pKa + log ( [A-]/ [HA]) 緩衝液のpHを求める際には One way to determine the pH of a buffer is by using the Henderson-Hasselbalch equation, which is pH = pKₐ + log ( [A⁻]/ [HA]). In this equation, [HA] and [A⁻] refer to the equilibrium concentrations of the conjugate acid-base pair used to create the buffer solution. When [HA] = [A⁻], the solution pH is equal to the pKₐ of the acid. What is the Henderson-Hasselbalch Equation? The Henderson-Hasselbalch equation provides a relationship between the pH of acids (in aqueous solutions) and their pK a (acid dissociation constant). The pH of a buffer solution can be estimated with the help of this equation when the concentration of the acid and its conjugate base, or the base and the corresponding conjugate acid, are known. |irr| agz| fyu| rct| iki| zcx| slp| vtq| dvt| lon| xrd| hxn| sxk| qfy| shh| jms| ukd| bev| ony| emm| kxx| dap| lov| ybn| hvl| rfb| kdp| dnq| ykz| hab| dxl| lkh| roq| yzk| eqj| eia| snp| qzc| bmk| hwf| ngs| ytu| jsd| iwt| hhd| vlm| rja| trl| fdq| aga|
