pH, pKa, and the Henderson-Hasselbalch Equation
WebStrong acids have a lower pH value. At equilibrium, the larger the Ka, the stronger the acid and the higher the H + concentration. Q6. State true or False. The equilibrium constant can be zero. Answer. ... = 10-(pKa) = Ka = Ka = 10-(pKa) Q14. Calculate the Ka of HClO if the given pH of 0.100 M HClO is 4.23. WebAug 5, 2024 · In addition to using pKa to gauge the strength of an acid, it may be used to select buffers. This is possible because of the relationship between pKa and pH: pH = … WebThis graph depicts the protonation state of acetic acid as the pH changes. At a pH below the pKa, the acid is protonated. At a pH above the pKa the acid is deprotonated. If the pH equals the pKa, the acid is 50% protonated and 50% deprotonated. Attribution: Ivy Jose.
