Understanding how to calculate the pH of a … WebAug 14, 2024 · The larger the Ka, the stronger the acid and the higher the H + concentration at equilibrium. Like all equilibrium constants, acid–base ionization constants are actually measured in terms of the activities of H + or OH −, thus making them unitless. The … Acids and bases have been known for a long time. When Robert Boyle …
4 Determination of pKa of weak acid using PH meter - YouTube
WebAs reported in the results, the weak acid was found to be CH3COOH, Acetic Acid. Conclusion The aim of this experiment was to identify the weak acid using the technique of titration and finding the Ka for comparison. Sodium Hydroxide of unknown concentration/molarity was standardized using KHP and added to the weak acid drop by … WebApr 26, 2013 · The pKa of an acid is exactly the same as the pH HALFWAY to the equivalence point!Then, Ka = 10^-pKa and you're done. Super easy.Thanks Henderson-Hasselbalc... edonokaze
