WebHowever it's unnecessary to calculate the pH of strong acid solution using the Henderson-Hasselbalch equation since we can do so using stoichiometry of H+ and assume that strong acids dissociate ~100%. So it's possible to use the Henderson-Hasselbalch equation, but it creates unneeded work when simpler methods are possible. Hope that helps. WebMar 6, 2014 · The molarity becomes the [H+] concentration of 3.2 × 10−3. We know this is the [H+] concentration because HNO3 is a strong acid, since the acid will completely dissociate into H+ and NO− 3. To find the pH calculate −log[H+] −log[3.2 × 10−3] = 2.49 = pH. To find the pOH take the pH value and subtract it from 14. 14 −2.49 = 11.51 = pOH. fear you don\\u0027t own me song

WebOne 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. Created by Jay. WebFeb 1, 2015 · pH = pKa +log( [A−] [H A]) If you're not dealing with a buffer, then you must use the acid dissociation constant, Ka, to help you determine the pH of the solution. In this case, you need to determine [H +] in order to determine pH, since pH = −log([H +]) The value of the acid dissociation constant can be derived from pKa Ka = 10-pKa deborah south richardsonWebDec 24, 2024 · Using pH to Calculate a Concentration 1.
