Web(a) Derive the Henderson–Hasselbalch equation for a weak acid. [6 marks] (b) Explain two requirements of a titration process. [2 marks] (c) The steam iron process is used to generate hydrogen – gas mostly in connection with the hydrogenation of oils. 3Fe (s) + 4H 2O (g) ⇌ Fe 3O4 (s) + 4H 2 (g) ΔHo = -150 kJ Web5) And the derivation of the Henderson-Hasselbalch equation proceeds from that point, as shown above. Note that the Henderson-Hasselbalch equation pH = pK a + log [($] [’(] (Eq. 6) gives the same result as long as the ratio of [A $] / [HA] is the same. However, higher concentrations are desirable.

WebJun 8, 2024 · Graphing is one of the simplest ways to solve a system of linear equations. All you have to do is graph each equation as a line and find the point (s) where the lines … WebAboutTranscript. 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 … WebThis is so called Henderson-Hasselbalch equation (or a buffer equation ). It can be used for pH calculation of a solution containing pair of acid and conjugate base - like HA/A -, HA - /A 2- or B + /BOH. For solutions of a weak bases sometimes it is more convenient to use equation in the form. Both equations are perfectly equivalent and ... chuga translation
